Transition metal catalyzed cross-coupling reactions such as Suzuki-Miyaura 1 , Heck 2-10 , Stille , Hiyama, Negishi , and Sonogashira reactions are likely to be the most power tool for the formation of C-C bonds for the past four decades. All these reactions have shown their widespread applicability ranging from academic area to research. Some of the reactions have also been applied in pharmaceuticals, agrochemicals, and fine material industries. The Suzuki-Miayura cross coupling was remained the most attractive alternative for C-C bonds formation since its discovery in 1979. The wide range of applicability of this reaction is largely attributed to mild reaction conditions, broad range of functional group tolerance, easy access to organo-boron reagents, and their stability under air and moisture. Furthermore, boron compounds show low toxicity and easy to separate boron from the reaction mixtures. Phenanthridine (3.1) is a nitrogen heterocycle that is the basis of DNA-binding fluorescent dyes through intercalation. Ethidium bromide and propidium iodide are the examples of such intercalating dyes. Phenanthridine is an isomeric compound of acridine (3.2) (Fig. .1).
