One-step synthesis of conjugated enynenitriles from bromocyanoacetylene

Org Biomol Chem. 2017 Jul 19;15(28):6050-6056. doi: 10.1039/c6ob02590k.

Abstract

The chemical reactivity of bromocyanoacetylene has been evaluated for the first time by making it react with terminal alkynes and secondary amines in the presence of bis(triphenylphosphine)palladium dichloride and copper iodide as co-catalysts. This reaction provides new conjugated enynenitriles stereoselectively in one step in variable yields.
