A highly selective hydroalkynylation of internal alkynes with silylacetylenes giving 1,3-enynes was realized by use of a hydroxorhodium catalyst. As a key intermediate in the catalytic cycle, an alkynylrhodium(I) complex was isolated and investigated for its structure and reactivity.
通过使用氢氧鎓催化剂实现了内部炔烃与甲硅烷基乙炔的高度选择性的加氢炔基化,得到1,3-烯炔。作为催化循环中的关键中间体,分离出炔基铑(I)配合物,并对其结构和反应性进行了研究。
