A Brønsted acid Ph2P(O)OH can efficiently catalyze the reaction of a Pd(0) complex with an alkyne to produce a novel alkenyl(alkynyl)palladium complex via selective hydropalladation and ligand exchange processes. On the basis of this finding, an efficient Pd(0)/Ph2P(O)OH mediated head-to-tail dimerization of alkynes was disclosed.
一种布朗斯特酸Ph2P(O)OH可以有效催化Pd(0)络合物与炔烃的反应,通过选择性氢镍化和配体交换过程生成一种新型烯基(炔基)钯络合物。在这一发现的基础上,揭示了一种有效的Pd(0)/Ph2P(O)OH介导的炔烃头尾二聚反应。
