Abstract
The thiolates [(η5-C5H5)M(CO)3SRF](M = Mo or W; RF = CF3 or C6F5) react with acetylenes, RCCR (R = CF3, Me, or Ph) to give the formally electron-deficient π-acetylene complexes [(η5-C5H5)M(CO)(RC2R)SRF]. The bonding and isomerism in these complexes at low temperatures is discussed. On oxidation [(η-C5H5)MoO(CF3C2CF3)SC6F5] can be isolated. Trifluoropropyne reacts with the thiolates to give the acetylene complex [(η5-C5H5)Mo(CO)(CF3C2H)SC6F5] and cyclopentadienone complexes [(η5-C5H5)Mo(CO){(CF3C2H)2CO}SCF3] and [{(η5-C5H5)[(CF3C2H)2CO]SCF3}2].Keywords
