Nickel-catalyzed tetramerization of alkynes: synthesis and structure of octatetraenes.

Tsun-Cheng Wu1, Jheng-Jhih Chen, Yao-Ting Wu.   

Abstract

In the presence of a catalytic system comprised of NiBr(2)(dppe) and Zn, arylacetylenes undergo tetramerization to form linear octatetraenes, generally in good to excellent yields. The structure of the coupling products was verified by X-ray crystallography.
