Synthesis, Dynamic Behavior, and Bond Character of Hydrogen-Bridged Bis(silylene)tungsten Complexes

摘要

Previously, our group has reported the synthesis of donor-stabilized bis(silylene) complexes (Chart 1), which are regarded as important intermediates of 1,3-group migration on silyl(silylene) complexes. The bonding mode of these complexes is best described as the resonance of two canonical forms, in which a lone pair of the donor group is coordinated to the silylene silicon atom.
