Thermolysis of (2-oxacyclopentylidene)pentacarbonylchromium(0): evidence against free carbenes in thermal decomposition of metal–carbene complexes

Thermolysis of (2-oxacyclopentylidene)pentacarbonylchromium(0)(I) gives mainly the dimer and no cyclobutanone, a product characteristic of a free carbene; a bimolecular mechanism for decomposition of (I) is proposed based on kinetic studies.

Reactions of conjugate bases of metal carbene complexes with expoxides and with α-bromo esters

Abstract The reactions of the conjugate base of (methylmethoxycarbene)pentacarbonylchromium(0) with epoxides and with methyl bromoacetate give alkylated carbene complexes which cannot be obtained by previous synthetic routes.
