published in Aduance A C S Abstracts, April 15, 1994. 0276-7333/94/2313-2010~04.50/0 mechanism governs cyclotrimerization at all of these varied catalytic centers. The evidence for various mechanisms has been thoroughly reviewed by Wigley,l with particular reference to low-valent early (electropositive) transition metal centers. We have reported2 a series of studies where acetylene cyclotrimerization is effected at 25 "C by catalyst precursors containing the (triphos)Ir+ substructure (triphos = MeC(CH2PPh2)s). At the same time, we have reported on
