Synthesis of polymerizable vinyltriazoles: Development of an optimized one-pot strategy starting from 4-bromobutyne

Praud,Bootzeek,Blache

, p. 1138 - 1141 (2013/06/27)

The development and implementation of a safe and scalable process for the preparation of isomeric vinyl-1,2,3-triazoles under mild conditions are described. Key aspects of the route reside in a one-pot click-elimination procedure in aqueous media leading to simple work-up and purification steps with increased overall yields.
