Molecular Construction Using Carbene and Diboron Systems: Catalytic Transformation of C-C and C-Hetero Atom Bonds

Abstract

The thesis presents an unconventional approach for the molecular construction using carbenes as the carbon source, and water as the hydrogen source. A gold-catalyst has been used to transfer the carbenes to effect [2,3]-sigmatropic rearrangement; and tris(pentafluorophenyl)borane-catalyst for the C-C bond functionalization and carbonate transfer reactions. On the other hand, a Pd-catalyzed stereodivergent reduction of alkynes has been achieved using water. The mechanistic details of the hydrogenation have also been probed, and the derived understanding has been applied to construct C-C bonds
