✦ Synopsis

Cobalt@) bound to copolymer of maleic acid and ethyl vinyl ether, crosslinked with 10 mol% 1,6-hexamethylene-d&nine was found to catalyze the oxidation of 2-styryl-1,3dioxane

and its alkyl substituted derivatives as well as 4,5-dimethyl-2-styryl-1,3-dioxolane affording hydroxy-alkyl-cinnamates. The effect of polymeric Co@) complex on the regioselectivity of the oxidation of 4-methyl-2-styryl-1,3-dioxane and cis-syn 4,5-dimethyl-2-styryl-1,3dioxolane was observed. A free-radical mechanism is proposed.

Measurements were made of the value of the lumped kinetic constant k p /k t 0.5 of vinyl acetate in different solvents and with different initiators. This quantity was evaluated using the well-known conversion vs. time approach in dilute solutions using both azo-bis-isobutyronitrile and benzoyl pero
