Conversion of Metallabenzynes into Carbene Complexes

Abstract

Osmabenzynes are shown to rearrange to carbene complexes. This previously unknown reaction of metallabenzynes, in analogy to the well-known formation of cyclopentadienyl complexes from metallabenzenes, has thus now been achieved. A subtle change in the substituents in the metallacycle can have a drastic effect on the transformation, as seen by the relative thermal stability of 1 and 2 (see scheme).
