Abstract
Dimethyldioxirane (DMDO) oxidizes the coordinated alkyne ligand in (RC p)Mn(CO)(2)(diarylalkyne) (3) to give moderate yields of the correspon ding alpha-keto carbene complex (RCp)Mn(CO)(2)(C(Ar)C(O)(Ar)) (5), thu s illustrating the synthetic potential of dioxiranes for the controlle d oxidation of coordinated ligands. The transformation 3 --> 5 might i nvolve initial alkyne epoxidation to give an intermediate containing a coordinated oxirene ligand.
