Coupling electrocatalysis (electron transfer chain) with organometallic catalysis: polymerisation of terminal alkynes catalysed by [W(CO)3(NCMe)3] and [Fe(cp)2]+PF6–(cp =η5-cyclopentadienyl)

Terminal alkynes (RC2H; R = Ph, Bun) are instantaneously polymerized at 20 °C by 1% of W(CO)3(NCMe)3(1) and 0.01% of [Fe(cp)2]+PF6–(2) in a system which couples electrocatalysis (electron transfer chain) with organometallic catalysis (cp =η5-cyclopentadienyl).
