Abstract

Treatment of a κ-P-monodentate bicyclic diphosphane iridium(III) complex with a labile gold(I) precursor afforded an unusual Ir/Au complex in which the P-P single bond has been cleaved. This reaction was cleanly reversed upon addition of tertiary phosphine. Carbon-carbon bond activation, across neighbouring PCN rings of the coordinated bicyclic diphosphane, occurred upon thermolysis of the Ir/Au complex.

摘要

用一种不稳定的金（I）前体处理κ-P-单齿双环二膦铱（III）配合物，得到了一种不寻常的Ir/Au配合物，其中P-P单键已被切断。加入叔膦后，该反应可完全逆转。在Ir/Au配合物热解时，配位双环二膦相邻的PCN环之间发生了碳-碳键活化。
