二甲基二氧环烷（DMDO）氧化（RCp）Mn(CO)(2)（二芳基炔）(3)中的配位炔配体，得到相应的α -酮-羰基配合物（RCp）Mn(CO)(2)(C(Ar)C(O)(Ar))(5)，从而说明了二氧环烷在配位配体的可控氧化方面的合成潜力。3—bbb50的转变可能涉及初始炔环氧化反应，得到含有配位环氧烷配体的中间体。
Dimethyldioxirane (DMDO) oxidizes the coordinated alkyne ligand in (RCp)Mn(CO)(2)(diarylalkyne) (3) to give moderate yields of the corresponding alpha-keto carbene complex (RCp)Mn(CO)(2)(C(Ar)C(O)(Ar)) (5), thus illustrating the synthetic potential of dioxiranes for the controlled oxidation of coordinated ligands. The transformation 3 --> 5 might involve initial alkyne epoxidation to give an intermediate containing a coordinated oxirene ligand.
