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