Applications

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.

Notes

Store in a cool dry place in tightly closed containers. Incompatible with oxidizing agents.
