Clemmensen Reduction. XI. Fragmentation Reactions of Some 3-Acetylcycloalkanones

Article abstract of DOI:10.1071/CH9951827

Clemmensen reduction of a series of 3-acetylcycloalkanones yields, as the major product, an acyclic unsaturated ketone, the product of fragmentation.Some normal carbonyl-methylene reduction also occurs.A mechanistic rationale for the fragmentation is advanced.
