Intermolecular alkynyl-ligand migration from aryl-palladium(II) to -platinum(II) complexes with and without a CuI catalyst. Reversible transfer of the alkynyl group between copper(I) and palladium(II) complexes

Abstract

Alkynyl-ligand transfer from [PdR(C≡CPh)L₂] (R = C₆H₄Me-p, L = PEt₃) to [PtR′(I)L₂] (R′ = C₆H₄OMe-p), to give [PdR(I)L₂] and [PtR′(C≡CPh)L₂], has been enhanced to a large extent by addition of CuI, indicating reversible ligand transfer between Pd^II and Cu^I complexes.
