Abstract

Reaction of copper(I) thiocyanate with 1,1′-bis(di-tert-butylphosphino) ferrocene (dtbpf) in a 2 : 1 molar ratio in DCM–MeOH (50 : 50 V/V) afforded a tetranuclear copper(I) complex [Cu4(μ3-SCN)4(κ1-P,P-dtbpf)2] (1) with a cubane-like structure. Complex 1 was shown to be an efficient catalyst in comparison to CuI in the Sonogashira reaction. The coupling products were obtained in high yields by using Pd loadings of 0.2 mol% as well as complex-1 of 0.1 mol%.
