Abstract
The frustrated Lewis pair P(o-tolyl)(3)/B(C(6)F(5))(3) reacts with 1,7-octadiyne by acetylene C-C coupling to yield the zwitterionic product 2a. In contrast, the P(o-tolyl)(3)/B(C(6)F(5))(3) Lewis pair reacts with 1,6-heptadiyne by a sequence involving 1,1-carboboration of a terminal acetylene to eventually yield the heterocyclic product 4.
摘要
受阻路易斯对 P(o- 甲苯基)(3)/B(C(6)F(5))(3)与 1,7-辛二炔通过乙炔 C-C 偶联反应生成两性离子产物 2a。相比之下，P(o- 甲苯基)(3)/B(C(6)F(5))(3)路易斯对与 1,6-庚二炔通过一系列反应，包括末端乙炔的 1,1-碳硼化反应，最终生成杂环产物 4。
