| Outline of Final Research Achievements |
Silanonetungsten and -molybdenum complexes were successfully synthesized by oxygenation of silyl(silylene) complexes with 1 eq of pyridine-N-oxide (PNO) in the presence of 4-(dimethylamino)pyridine (DMAP). The reactivities of the silanone complexes were investigated with MesCNO, cyclotrisiloxane, MeOH, and H2O. Reaction with H2O afforded different main products for the tungsten and molybdenum complexes. Theoretical investigation revealed that the product difference arises from the difference of electrophilicity of the silicon atom in silanone ligand and that of the lability for oxidative addition of water across the M-silanone framework.
