Silylethynylthiophenes were obtained from palladium-catalyzed alkynylation of various thiophenes with 1-halo-2-silylacetylenes. The α-position of thiophenes was alkynylated with high regioselectivity. The terminal silyl groups of products could be replaced by several functional groups.
甲硅烷基乙炔基噻吩是由各种噻吩与1-卤-2-甲硅烷基乙炔的钯催化炔基化反应制得的。噻吩的α-位被炔基化,具有很高的区域选择性。产品的末端甲硅烷基可以被多个官能团取代。
