Treatment of pyridine-stabilized silylene complexes [(η5-C5Me4R)(CO)2(H)W=SiH(py)(Tsi)] (R=Me, Et; py=pyridine; Tsi=C(SiMe3)3) with an N-heterocyclic carbene MeIiPr (1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene) caused deprotonation to afford anionic silylene complexes [(η5-C5Me4R)(CO)2W=SiH(Tsi)][HMeIiPr] (R=Me (1-Me); R=Et (1-Et)). Subsequent oxidation of 1-Me and 1-Et with pyridine-N-oxide (1 equiv) gave anionic η2-silaaldehydetungsten complexes [(η5-C5Me4R)(CO)2W{η2-O=SiH(Tsi)}][HMeIiPr] (R=Me (2-Me); R=Et (2-Et)). The formation of an unprecedented W-Si-O three-membered ring was confirmed by X-ray crystal structure analysis.
