在铑催化剂作用下，内炔与硅炔发生高选择性的氢化炔基化反应，生成1，3-烯炔。作为催化循环的关键中间体，炔基铑（I）配合物的分离和研究其结构和反应性。
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.
