M. VANDEWALLE, N. SCHAMP and H. DE WILDE ... 2-Acyl-2-halogenocyclopentane-1,3-diones are obtained in high yield, starting from 2-acylcyclopentane-l,3-diones. Their degradation and isomeration products are described. ... Recently several methods ('* '* 3, for the synthesis of 2-acylcyclo- pentane-1,3-diones (I) have been developed. This is a report on the formation and properties of some of their halogen derivatives. A bromine or chlorine atom can be ...
