Abstract

A tungsten silylyne complex having a fused-ring group (Eind) on Si was synthesized from a hydrido hydrosilylene complex via stepwise abstraction of a proton and a hydride and was isolated as an eight-membered cyclic dimer bound through two isocarbonyl linkages. The IR and variable-temperature NMR analyses revealed that the dimer is in equilibrium with a monomeric silylyne complex in solution. The silylyne complex underwent [2 + 2] cycoaddition reactions with carbodiimide and diaryl ketones, and in the latter case the cycloaddition product further reacted with another molecule of ketone to give a complex formed through C-C and Si-C coupling.
