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.
布朗斯特酸 Ph2P(O)OH 可以有效地催化 Pd(0) 配合物与炔烃的反应，通过选择性的加氢钯化和配体交换过程，生成新型的烯基（炔基）钯配合物。基于这一发现，我们揭示了一种高效的 Pd(0)/Ph2P(O)OH 介导的炔烃的头尾二聚反应。
