First row transition metal complexes (Ni, Co, Cu, Zn) with N,N-disubstituted-N′-acylthiourea ligands have been synthesized and characterized. Bis(N,N-diisopropyl-N′-cinnamoylthiourea)nickel was found to have the lowest onset temperature for thermal decomp

Rhodium(I) carbonyl complexes containing bidentate X,O-Bid [S,O-BdiPT or N,O-ox; S,O-BdiPTH = N-benzoyl-N′,N′-(diphenyl)thiourea; N,O-oxH = 8-hydroxyquinoline] ligands of the form [Rh(X,O-Bid)(CO)(PR1R2R3)] (R1, R2, R3 = Ph or Cy) bearing different phosphine ligands, were investigated, the structural characterization of four example complexes is described and an extensive spectroscopic kinetic-mechanistic study of the oxidative addition of iodomethane thereto is discussed. Reaction with iodomethane led to RhIII-acyl species as secondary (final) products, whereas the primary RhIII-alkyl complexes, although rapidly formed, were only observed as intermediates, in small quantities for S,O-BdiPT (large S–Rh–O bite angle of 90–91°) but in significant amounts for N,O-ox complexes (less steric with a smaller N–Rh–O bite angle of 79–80°). Overall, almost an order-of-magnitude difference in rate constants was observed for the S,O-BdiPT complexes, with the PPh2Cy- and PPhCy2-bearing complexes showing the largest variation. In both the S,O-BdiPT and N,O-ox ligand systems an associative activation is inferred from the large negative ΔS≠ values. The relative reactivity of RhI-X,O-Bid complexes, where X = O, S or N, follows a surprising similar reactivity relationship when stepwise varying the PPh3, PPh2Cy, PPhCy2 and PCy3 tertiary phosphine ligands, suggesting a systematic behavior by the PR3 ligands, independent of the X,O-Bid ligand at the RhI metal center.
