Research Abstract

Transition-metal-catalyzed bond-forming reactions of unsaturated organic substrates with silylene, divalent silicon species, was established, in which silylboronic esters were used as thermally stable and storable silylene precursors. We also found that addition reactions of boron reagents took place efficiently into nitrogen-containing aromatic compounds in the presence of a transition metal catalyst to give dearomatized products. It was suggested that a key accelerating factor in these catalytic processes was boron-nitrogen bond formation.
