Abstract
Two Ru(II)-catalytic systems were developed for anti-Markovnikov regioselective hydroacyloxylations of terminal alkynes to vinylic esters. [Ru(NCCH)][(BF)] favors ()-vinylic ester products with arylacetylenes and select carboxylic acids, whereas a Ru scorpionate complex with two electron-withdrawing ligands favors ()-vinylic ester isomers.
摘要
开发了两种钌（II）催化体系，用于将末端炔烃进行反马氏区域选择性氢酰氧基化反应生成乙烯基酯。[Ru(NCCH)][(BF)]有利于芳基乙炔与特定羧酸生成（）-乙烯基酯产物，而带有两个吸电子配体的钌（II）螯合物有利于生成（）-乙烯基酯异构体。
