Abstract:
An expedient procedure is reported for the preparation of the synthetically valuable Au(i) complex [Au(MeCN)(PtBu2C6H4Ph-2)][BF4] (Echavarren's catalyst) directly from gold powder using [NO][BF4] in acetonitrile. The synthetic method obviates the potential presence of silver or halide impurities that follow from the tedious conventional synthesis, and have otherwise been shown to moderate catalyst performance.
