α-Hydroxy acids react with terminal alkynes, in the presence of binuclear ruthenium complexes [Ru(μ-O2CR)(CO)2 (PPh3)]2 as catalyst precursors, to selectively afford either α-hydroxy enol esters or their cyclization products 1,3-dioxolan-4-ones.
α羟基酸与末端炔烃反应,在双核钌络合物的[Ru(μ-O存在2 CR)(CO)2(PPH 3)] 2作为催化剂前体,以选择性地得到任一α羟基烯醇酯或它们的环化产物1,3-二氧戊环-4-酮。
