Abstract : Carbodiimides are an significant class of cumulene-type nitrogenous compounds that serve as crucial intermediates and precursors in the synthesis organic molecules. They have drawn considerable attention among the organic chemists because of their easy availability, exceptional chemical activities and wide-ranging applications, particularly in the synthesis of nitrogen containing heterocycles. Due to their versatile applications, considerable research has focused to the development of new methodologies for the synthesis of functionalized carbodiimides; particularly by employing hypervalent iodine reagents and transition metal-catalysts. Recently, we reported a review article for the synthesis of carbodiimides using hepervalent iodine as reagents. In recent years, the transition metal catalyzed oxidative coupling of azides and isocyanides has emerged as an attractive method for the construction carbodiimides via nitrene transfer mechanism. In this review, we discuss recent advances in the transition metal-catalyzed synthesis of carbodiimides, highlighting innovative strategies and mechanistic insights.

Keywords : Carbodiimides, Azides, Isocyanides, Transition Metal Catalysts, Palladium, Chromium and Iron.
