Whereas silicon divalent species (silylenes) are usually generated as reactive intermediates in numerous thermal and photochemical reactions of organosilicon compounds, 1 has been available as a sole isolable dialkylsilylene since 1999.1 Silylene 1 has been revealed not only to be valuable to undestand unique bonding and properties of silylene but also useful as a regaent for the synthesis of hardly accesible unsaturated silicon compounds including silaketeneimines, a silanethione, and a trisilaallene.
In the present talk, some recent studies of its new reactions with carbon -hetroatom doubly bonded compounds such as imines, benzonitriles, diazocarbonyl compounds, and carbon dioxide and their mechanistic aspects are discussed, in addition to a brief summary of the synthesis, structure, and properties of 1.
