Abstract

Cross-dimerization of various terminal alkynes with different bulky terminal alkynes such as triisopropylsilylacetylene and 1-trimethylsilyloxy-1,1-diphenyl-2-propyne efficiently proceeds in the presence of a rhodium catalyst system to produce the corresponding (E)-enynes with high regio- and stereoselectivity.

摘要

在铑催化剂体系存在下,各种末端炔烃与不同的大位阻末端炔烃(如三异丙基硅基乙炔和1-三甲基硅氧基-1,1-二苯基-2-丙炔)的交叉二聚反应能高效进行,以高区域选择性和立体选择性生成相应的(E)-烯炔。
