Abstract

The enthalpies of the following reactions have been measured by solution calorimetry: HMo(CO)₃C₅H₅+EtMo(CO)₃C₅ H₅ →EtC(O)H+ 1 2[Mo(CO)₂C₅H₅]₂+ 1 2[Mo(CO)₃C₅H₅]₂ [Mo(CO)₂C₅H₅]₂+2PR ₃→[Mo(CO)₂(PR₃) C₅H₅]₂ PR₃ = P(OMe)₃ and P(C₆H₅)₂Me RMo(CO)₃C₅H₅+I₂→R;I+IMo(CO)₃C₅H₅ R = C₆H₅CH₂, H₂CCHCH₂ R = Mo(CO)₃C₅H₅+PR₃→RC(O)Mo (CO)₂(PR₃)C₅H₅ R = C₆H₅CH₂ PR₃ = PMe₃, PMe₂Ph, PMePh₂, PPh₃, P(OMe)₃. The results from this work are combined with earlier data to generate estimates for MoX bond strengths (X = H, Cl, Br, I, CH₃, C₂H₅, C₃H₅ and PhCH ₂). The influence of phosphine substitution on the thermochemistry of model catalytic reactions is discussed.
