Nickel and Palladium Catalyzed Denitrogenative Reaction of 1 2 3 Benzotriazin 4 3h One for Synthesis of Ortho Functionalized Benzamides and Heterocyclic Compounds

Abstract

Organometallic compounds are increasingly being used to mediate or catalyze reactions in the synthesis of pharmaceuticals and fine chemicals. In this context, Palladium- catalyzed cross-coupling reactions are extremely useful for the construction of organic molecules in both academia and industry. Palladium-catalyzed cross-coupling reactions are coupling reactions that take place between an electrophile and a nucleophile (usually an organometallic reagent) and are catalyzed by palladium precursors. Organo halides, such as organo iodides and bromides, have traditionally been used as electrophiles in cross-coupling reactions. Despite the fact that organo iodides and bromides were excellent synthons, their cost and availability limited their utility. Because of this, organo pseudo halides including oxo-sulfonates and aza-sulfonates have been successfully used in transition metal-catalyzed cross-coupling reactions to form various C-C bonds. Even so, these electrophiles can produce an unavoidable amount of waste. Disposal of this waste has been a major issue for industries in bulk scale synthesis. As a result, there is a pressing need to improve environmentally friendly cross-coupling reactions. Triazoles would be regarded as excellent synthons for organic synthesis in this case. In denitrogenative transformation, these will expel eco-friendly molecular nitrogen as a by-product. Triazoles can deliver a variety of nitrogen-containing organic compounds in an efficient and regioselective manner on cross- coupling reactions with various nucleophiles. In this regard, 1,2,3-Benzotriazin-4(3H)-one is a well-known triazole molecule that can be used in a variety of pharmaceuticals and agrochemicals newline
