Abstract

The reaction between the conjugate bases of (2-oxacyclopentylidene)pentacarbonyl-chromium(0) complexes 1a-f and N,N-dimethylmethyleneammonium hydrochloride directly leads to the corresponding exo-methylene derivatives 3a-f in satisfactory yields. As an example, compound 3d has been oxidized to alpha-methylene-gamma-butyrolactone 4
