Abstract : A series of (eta(5)-pentamethylbenzyl)manganese dicarbonyl phosphite complexes have been synthesized. Manganese-coordinated phosphites react with the exocyclic methylene of the coordinated pentamethylbenzyl ligand generating either benzyne or a carbene, an eta(6)-hexaalkylbenzene, and dialkyl- or diaryl phosphonate complexes. Their decomposition to phosphonates was observed under reduced pressure or in the presence of olefins. Benzyne, from the triphenylphosphite complexes was observed indirectly through the formation of diphenylene. The production of methylene carbenes was observed by the formation of ethene and cyclopropanes. The generation of olefins or cyclopropanes indicated that ethylidene was produced
