For more than a decade vinylgold(I) compounds were written as intermediates in gold-catalysed reactions of alkynes and allenes, but only now the experimental proof for their participation in catalytic cycles could be obtained. This includes preparative access to these species, which for the first time allows to expand this aspect of organogold chemistry in new directions.

可分离的乙烯基金中间体——首次获得均相金催化的幻影

十多年来，乙烯基金 (I) 化合物被认为是炔烃和丙二烯的金催化反应的中间体，但直到现在才能获得它们参与催化循环的实验证据。这包括对这些物种的准备访问，这首次允许将有机金化学的这一方面扩展到新的方向。
