Standard heats of formation and M–C bond energy terms for some homoleptic transition metal alkyls MRn

Abstract

The heats of alcoholysis in isopropyl alcohol of the d0 Ti or Zr compounds MR4(R = Me3SiCH2, Me3CCH2, or PhCH2), M(NR′2)4(R′= Me or Et), and MCl4(and some Hf analogues) have been measured, as well as the heats of solution in Pr1OH of M(OPri)4, RH, R′2NH, or HCl; from these and subsidiary data standard heats of formation and thermochemical mean bond energy terms have been derived [M–X in kcal mol–1: Ti–Cneopentyl,44; Ti–C,63; Ti–N, 81; Ti–O, 115; Zr–Cneopentyl, 54; Zr–C, 74; Zr–N, 90; Zr–O, 132; Hf–Cneopentyl, 58; Hf–N, 95; Hf–O, 137].
