Abstract
Various cyclic alpha,beta-epoxy ketones rearranged to alpha-formyl ketones and/or vic-diones in the presence of catalytic amounts of zeolites and mont morillonite K10. This provides an excellent alternative to conventional hom ogeneous systems with respect to yields and workup. Differences in product distribution and type of products in the rearrangement of pulegone oxide co uld be reasonably explained by invoking different pathways for homogeneous and heterogeneous catalysts.
