Abstract

(Chemical Equation Presented) Novel η3-silapropargyl/ alkynylsilyl complexes Cp*(CO)2Mo(η3-Ph 2SiCCR) (3a, R = tBu; 3b, R = iPr) were synthesized by the reactions of Cp*(CO)2(MeCN)MoMe (1) with alkynylsilanes HPh2SiC≡CR. The structures of 3a and 3b were fully characterized by NMR spectroscopy and X-ray crystallography. The reaction of 3a with MeOH at room temperature gave the stable four-membered metallacycle Cp*(CO)2MoC(=CHtBu)SiPh2OMe (5a), while the corresponding reaction of 3b led to the formation of the η3-allyl complex Cp*(CO)2Mo{η3- (MeOPh2Si) HCCHCMe2} (7) via Cp*(CO) 2MoC(=CHiPr)SiPh2OMe (5b).
