Abstract

A simple method has been developed for homocoupling of terminal alkynes bearing different functional groups by reaction with CuI/tribromoisocyanuric acid/piperidine in acetonitrile at room temperature. A telescoped approach based on Hunsdiecker/Cadiot–Chodkiewicz reactions for C(sp)-C(sp) cross-coupling was also presented.

三溴异氰尿酸作为通过Glaser偶联合成1,3-二炔的有用氧化剂

摘要

通过在室温下与CuI /三溴异氰尿酸/哌啶在乙腈中反应，已开发出一种简单的方法，用于对带有不同官能团的末端炔进行均偶联。还提出了一种基于Hunsdiecker / Cadiot-Chodkiewicz反应的C（sp）-C（sp）交叉耦合的望远镜方法。
