BACKGROUND OF THE INVENTION 
     The Epoxy Intermediates and resins industry (Encyclopedia of Chemical Technology, Volume 9, Fourth Edition, John Wiley &amp; Sons Page 370) is a multibillion dollar business that is based on the following technology that involves no less than ten chemical reactions.
     Benzene+propylene→isopropyl benzene   Isopropyl benzene→cumene hydroperoxide   Cumene hydroperoxide→phenol+acetone   Phenol+acetone→“Bis-A” or ( Phenol+formaldehyde→“Bis-F”)   Propylene+chlorine→allyl chloride   Allyl chloride+sodium hydroxide+chlorine→propylene chlorohydrins   Propylene chlorohydrins+sodium hydroxide→epichlorohydrin   Bis-A+epichlorohydrin+NaOH→“Bis-A glycidol ether”   Bis-A glycerol ether+Bis-A→epoxy resin   Sodium chloride+water→chlorine+sodium hydroxide   

     Several aspects of the above reaction sequence have negative process implications with regards to yields, chlorinated byproducts, hydraulic load and biological hazards. These include but are not limited to the following: (a) benzene is a known carcinogen, (b) Bis-A is an endocrine disrupter (mimics estrogen). Recent research (Current Biology, Volume 13, page 546, 2003) has shown that abnormalities in developing mouse eggs occurred at levels of bisphenol A to which people are commonly exposed. Similar aberration in human eggs would lead to miscarriages and birth defects, and (c) chlorination of propylene to allyl chloride and the addition of hypochlorous acid to allyl chloride yield higher chlorinated byproducts resulting in ˜⅓ pounds of chlorinated waste per pound of epichlorohydrin. In addition, the process requires a chlor-alkali facility, hence a local hence a local source of salt and huge volumes of water. The products and processes of the present invention ameliorate if not eliminate some of the disadvantages of prior art of epoxy products and processes. 
     BRIEF DESCRIPTION OF THE INVENTION 
     The present invention relates to the preparation of ethers and esters of diallylphenols and the epoxidation of the diallyl moiety to provide bis-epoxide ether and ester intermediates useful in the preparation of epoxy resins. The epoxy ethers and esters of carboxylic, carbonic, phosphoric and sulfuric acids of the present invention are represented by the following formulas: 
                                
where Ar is a trivalent aromatic radical of 6–20 carbon atoms, Ar′ is a bridged diaromatic radical having the formula Ar—Y—Ar and Y is O, CO, S, SO 2 , —(CH 2 )y , or —C(R″) 2 — and y is from 0 to 6, and R and R′ are the same or different alkyl, aryl, alkylene aryl, arylene alkyl, alkylene alkoxy, alkylene aryloxy, arylene alkoxy and arylene aryloxy aryl, radicals having from 6–20 carbon atoms, X is —R, —COR, —COOR, —SO 2 R, —PORR′and R″ is methyl.
 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     The synthesis of diepoxides described in the present invention requires the introduction of the allylic moiety to the aromatic ring that is converted in a subsequent reaction to the 2,3-epoxypropyl moiety. The allylation of phenols is well documented in the literature utilizing allyl aryl ethers, that on heating, rearrange to allyl phenols. The reaction is called the Claison Rearrangement (Advanced Organic Chemistry, 3 rd  Edition, by J. March, John Wiley &amp; Sons 1985). Allyl aryl ethers are readily prepared from the phenate salt and allyl derivatives.
     C 6 H 5 OH+CH 2 ═CHCH 2 X+base→C 6 H 5 OCH 2 CH═CH 2  where X=chloride, bromide, acetate, tosylate etc.   C 6 H 5 OCH 2 CH═CH 2 +heat→CH 2 ═CHCH 2 —C 6 H 5 OH
 
The preparation of the novel diepoxides described in the present invention utilizes the Claison rearrangement and the allyl ether synthesis in one of two ways depending on the structure of the aromatic substrate. If the starting aromatic is a monophenol, the allylation-rearrangement is carried out a second time to obtain the diallyl product as illustrated below for phenol.
   Phenol+allyl chloride+base→allyl phenyl ether   Allylphenyl ether+heat+solvent→2-allyl phenol   2-allyl phenol+allyl chloride→2-allyl phenyl ether   2-allyl phenyl ether+heat+solvent→2,6-diallyl phenol
 
The diallylphenol is derivatized to either the desired ether or ester and oxidized to the diepoxide with a peracid, hydrogen peroxide/catalyst, t-butyl hydroperoxide/catalyst system that are well documented in the literature. If the starting aromatic is a diphenol, the latter is diallylated to the bis ether and rearranged as described above to the diallyl diphenol. Derivatization to either a diether or diester as described above followed by oxidation yields the desired diepoxide. The latter process with diphenols is advantageous in that two process steps are eliminated (an allylation and a rearrangement). The following are examples of phenols and diphenols that may be used as starting materials for the invention: phenol, 4-methoxyphenol, 4-methylphenol, 2,6-dichlorophenol, 2-naphthol, 4-cyanophenol, 4-hydroxybiphenyl, 4-tert.butyl phenol, 4-dodecylphenol, 3-butoxyphenol, 3,5-dimethylphenol, 3-trifluoromethylphenol, 2,4-diethylphenol, catechol, hydroquinone, resorcinol, 2,2-(4-hydroxyphenyl)propane, 4,4′-sulfonyldiphenol, 4,4′-dihydroxybenzophenone, 4,4′-hydroxyphenylmethane, 4-hydroxyphenyl ether, 2-hydroxyphenylthioether, 4,4′dihydroxybiphenyl.
   

     The condensation of the bis-epoxides of this invention with diphenols, e.g., bis-phenol-A, bis-phenol-F,4-hydroxyphenyl sulfone, 4,4* dihydroxybenzophenone, 4,4′dihydroxybiphenyl, and 1,4-(4-hydroxyphenyl)butane, with dicarboxylic acids, e.g., isophthalic acid, succinic acid and cyclohexane dicarboxylic acids, with amino phenols, e.g, 4-aminophenol, 4-amino-4*-hydroxyphenylether, and 4-amino-4′-hydroxybiphenyl, with hydroxycarboxylic acids, e.g., 4-hydroxybenzoic acid, and 6-hydroxy-2-naphthoic acid, with amino acids, e.g., 4-aminobenzoic acid, with diamines, e.g., 4,4′-diaminophenyl ether, 1,3-diaminobenzene and 1,3-diaminopropane or with disulfonamides, e.g., 1,3-benzenedisulfonic acid: bis-N-methylamide results in new and valuable epoxy resins for protective coatings, structural composites, electrical laminates and adhesives. The chemistry provides the opportunity to manufacture resins with fewer chemical transformations, less capital and a reduction in the waste load associated with the bis-A epichlorohydrin technology. The resins can be obtained from the bis-epoxides using condensation procedures known in the art. An example of a resin synthesis from readily available starting materials using the diepoxide route of the present invention is outlined below:
     1. Toluene→phenol (T. Shikada, et al J. Chem. Soc., Chem. Commun, 1994)   2. Propylene→allyl acetate   3. Phenol+sulfuric acid→4,4′- sulfonyldiphenol   4. 4,4′-Sulfonyldiphenol→4-alloxyphenyl sulfone   5. 4-Alloxyphenyl sulfone→3-allyl-4-hydroxyphenyl sulfone   6. 3-Allyl-4-hydroxyphenyl sulfone→3-allyl-4-methoxyphenyl sulfone   7. 3-Allyl-4-methoxyphenyl sulfone→3- (2,3-epoxypropyl)-4-methoxyphenyl sulfone   8. 3- (2,3-Epoxypropyl)-4-methoxyphenyl sulfone+(diphenol, diacid, etc.,)→epoxy resin

     EXAMPLE 12  
     PREPARATION OF 4-METHOXY-3-(2,3-EPOXYPROPYL)PHENYL SULFONE 
     4,4*-Sulfonyldiphenol (25 gm, 0.10 mol) was dissolved in methanol (200 ml) and sodium hydroxide (8.0 gm, 0.20 mol) was added and stirred until the solution was homogeneous. Allyl chloride (20 mL 0.25 mol) was added and the solution heated and stirred at ˜45° C. until the reaction was complete. The reaction was poured onto water and extracted with ethyl acetate. The organic extract was washed with water (2×), dried, recrystallized from aqueous acetone to give 4-alloxyphenyl sulfone, mp 140–142° C. MS m/z 330 (M+ calcd for C 18 H 18 O 4 S=330).

When the solution was homogeneous, methyl iodide (3.87 gm, 0.028 mol) was added and the reaction mixture heated at ˜40° C. for 40 hr. The reaction was poured onto hexane. The hexane solution was washed with water (3×), dried over MgSO 4  and the solvent evaporated to give 4-methoxy-3-allylphenyl sulfone mp 82–85 C. MS m/z 358 (M+ calcd for C 20 H 22 O 4 S=358).
