COPPER (I) PHENYLACETYLIDE Chemical Properties,Usage,Production

Uses

Copper(I) phenylacetylide participates in efficient coupling with a range of aryl iodides and bromides to give substituted tolanes?which, if possessing an?ortho?amino or hydroxy group, can be thermolyzed to yield 2-phenylbenzofurans, -indoles, and -furo[3,2-b]pyridines.
