sankraman dhaatu isocyanide parisar

sankraman dhaatu isocyanide parisar isocyanide ligand vaale samanvaya yaugik hain. kyonki isocyanides apekshaakrit buniyaadi hain, lekin achche paaee-receptor bhee hain, isaliye parisaron kii ack vistrit shrinkhala gyaat haye. kuchh isocyanide parisaron kaa upayog chikitsa imaging mein kiya jaataa haye.
isocyanide ligand kaa daira.
kaee hazaar isocyanide gyaat hain, lekin samanvaya rasayan mein kuchh ligand kaa prabhutva haye. samanya isonitrile ligand methyl isocyanide, turt-butyle isocyanide, phenyl isocyanide aur cyclohexylisocinede hain.
isocyanide electronic roop seey koo key samaan hotey hain, lekin adhikansh aar samoohon key liye, isocyanide behtar luis bases aur kamjor paaee-receptor hotey hain. trifluoromethylisoine apavaad haye, isake samanvaya guna saha key samaan hain.
kyonki see. aine. see. kaa sambandh raikhik haye, inn ligand kaa shanku konn chhota haye, isaliye polyisocyanide parisaron koo taiyar karna aasaan haye. isocyanides key kaee parisar uchch samanvaya sankhyaaen dikhaate hain, jaise.jee. aathh-samanvit catayan. bahut bhaari isocyanide ligand bhee jaane jaate hain, ee.jee. c6h 3-2,6-ar2-nc (ar = aryl).
dee-aur trisocyanide ligand achchi tarah seey vikasit hain, ee.jee., (ch2) n (nc) 2. aamtaur parr steric kaarak inn ligand koo dou alag-alag dhatuon seey baandhane key liye majboor karate hain, i.ee.way binucleating ligand hain. chealeting diasocyanide ligand key liye vistrit backbones kii aavashyakta hoti haye.
sanshleshan.
unake cumm steric profile aur uchch kshaariyata key kaaran, isocyanide ligand aksar aasaani seey sthaapit hoe jaate hain, jaise.jee. dhaatu key halloid koo isocyanide key saath upchaarit karke. isocyanide parisar dene key liye kaee dhaatu sinide aine-alkylated hoe sakate hain.
pratikriyaaen.
aamtaur parr, isocyanides darshak ligand hotey hain, lekin unake cumm aur aukseekrit parisar ligand kii asantript prakriti key aadhar parr pratikriyaasheel saabit hoe sakate hain.
cashionic parisar carbon parr nucleophilic hamale key liye atisamvedansheel hotey hain. iss tarah, pahale dhaatu carbine parisar jahaan taiyar kiye gaye they. kyonki isocyanide sweekaar karane vaale aur daataa donon hain, way saha kii tulanaa mein okseekaran avasthaon kii ack vyaapak shrinkhala koo sthir karate hain. iss laabh koo teen okseekaran avasthaon mein homoleptic vanadium hexaisocyanide parisar key algaav dwara darshaaya gayaa haye, i.ee., n =-1,0, + 1 key liye [v (cnc6h 3-2,6 -me2) 6] n.
kyonki isocyanides saha kii tulanaa mein adhik buniyaadi daataa ligand hain, unake parisar okseekaran aur protonation key liye atisamvedansheel hain. iss prakaar, aasaani seey protonet kiya jaataa haye, jabaki iska samkaksh naheen haih
kuchh electron-samriddh isocyanide parisar aine parr protonet karate hain joe aminocarbine parisar dete hainh
isocyanides kabhi-kabhi dhaatu-alkyle bandhan mein imminosyls banaane key liye daalate hain.
sanrachana aur bandhan.
isocyanide parisar aksar dhaatu carbonyl kii sanrachanaon aur stoichiometry koo pratibimbit karate hain. saha kii tarah, isocyanides paaee-backbonding mein sanlagn hotey hain. aim-see-aine konn backbonding kii degree kaa kuchh maap pradaan kartaa haye. electron-samriddh parisaron mein, yeh konn aamtaur parr 180° seey vichalit hotaa haye. saha key vipareet, cashionic aur dicationic parisar aam hain. aar. aine. see. ligand aam taur parr antim hotey hain, lekin aar. aine. see. ligand koo jodana aam haye. bridging isocyanides hamesha mudey hotey hain. pahali pankti sankraman dhatuon key samasthaanik parisaron key nireekshan dwara samanya rujhaanon kii sarahana kii jaa sakati haye.
ir spectroscopy.
isocyanides mein νc shnan baind 2165-2110 cm−1 kii seema mein teevra haye. νc shnan kaa moolya jatil key electronic charitra kaa nidan haye. una parisaron mein jahaan aar. aine. see. mukhya roop seey ack sigma daataa ligand haye, νc shna aine uchch oorjaa banaam mukt isocyanide mein sthanantarit hoe jaataa haye. iss prakaar, νc shnan = 2152,220 semi − ell key liye. isake vipareet, electron-samriddh prajaati phee2 (senate) 9 key liye, νc shnan = 2060,1920,1701,1652 semi − ell.
