Synthesis of .beta.-Lactones by the Photochemical Reactions of Chromium Alkoxycarbene Complexes with Aldehydes
摘要:
Photolysis of chromium alkoxycarbene complexes with aldehydes in the presence of Lewis acids produced beta-lactones in low yield. Incorporation of the aldehyde into either side chain of the carbene complex resulted in intramolecular processes which were considerably more efficient.
