Synthetic Applications of Lawesson’s Reagent in Reactions with CuI Alkoxides

Abstract

AbstractThe reaction of Lawesson’s reagent with CuOtBu and tertiary phosphanes produced the complexes [Cu2(μ2‐ArS2P–O–PS2Ar)(PPh3)4] (1) (Ar = p‐C6H4OMe) and [Cu4{Ar(μ2‐S)2P–O–P(μ2‐S)2Ar}2(dppa)2] (2) (dppa = Ph2PNHPPh2) in high yields. The ligand [ArS2P–O–PS2Ar]2– is the first of a new family of dianionic P/S ligands. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
