C-S bond activation of thioesters using platinum(0)

摘要

C-S bond activation of both cyclic and acyclic thioesters using (dippe)Pt(NBE)_2 (NBE = norbornene) are reported. In the cases of S-methyl thioacetate and S-ethyl thioacetate, (dippe)Pt(C(O)Me)(SR) (R = Me, Et) formed initially. Further heating in the presence of excess thioester led to formation of the final complex (dippe)Pt(SR)_2 along with acetone and RSMe as organic side products. Pt~(IV) intermediates are proposed to be involved in the reaction mechanism.
