  Calorimetric studies of the heats of protonation of the metal in Fe(CO)3(bidentate phosphine, arsine) complexes: effects of chelate ligands on metal basicity

  摘要：

  Titration calorimetry has been used to determine the heats of protonation (DELTA-H(HM)) of Fe(CO)3,(LL) complexes (LL = dppm, dppe, dppp, dppb, dppbz, cis-dppv, arphos, dmpm, dcpe, and diars) with CF3SO3H in 1,2-dichloroethane solution at 25.0-degrees-C. Spectroscopic studies show that protonation occurs at the metal center to form fac-[Fe(H)(CO)3(LL)]CF3SO3. For the series Fe(CO)3[Ph2P(CH2)nPPh2], n = 1-4, DELTA-H(HM) becomes less exothermic as the chelate size increases from n = 1 (-24.0 +/- 0.2 kcal mol-1) to n = 4 (-20.1 +/- 0.2 kcal mol-1). Moreover, the chelate complexes are substantially more basic than the related nonchelate complex Fe(CO)3(PPh2Me)2 (DELTA-H(HM) = -17.6 +/- 0.4 kcal mol-1). Likewise, Fe(CO)3(dmpm) is much more basic (DELTA-H(HM) = -30.2 +/- 0.4 kcal mol-1) than Fe(CO)3(PMe3)2 (DELTA-H(HM) = -23.3 +/- 0.3 kcal mol-1). The higher basicities of complexes with small chelate ligands are ascribed to distortions imposed on the Fe(CO)3(LL) complexes by the chelate ligand. Basicities of several other Fe(CO)3(LL) complexes are also discussed.
