Abstract

An inexpensive catalytic system, which used a readily available Fe (acac) 3 and trace quantity of Cu (acac) 2 as the co-catalyst and air as the oxidant for the homo-coupling of terminal alkynes, has been developed. The catalytic system could also apply to the cross- coupling reaction of two different terminal alkynes.
