Abstract

The reactions of benzene or toluene solutions of Ru11(TMP), where TMP is the dianion of 5,10,15,20-tetramesitylporphyrin, with some acetylenes and alkenes are reported. Acetylene yields the isolable [Ru(TMP)]2(mu-C2H2) species; while with phenylacetylene or diphenylacetylene, 1:1 pi-complexes are formed. The pi-complexes Ru(TMP)(C2H4) and Ru(TMP)(C2H4)(i)PrOH.(i)PrOH are isolated from reactions with ethylene, and a similar cyclohexene species is characterized in situ. The findings are relevant to O2-epoxidation of alkenes catalyzed by the trans-Ru(TMP)(O)2 complex.
