N2 - 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.
