UV-light- and γ-60Co-initiated addition of acetaldehyde to allyl formate (I) and allyl acetate (II) yielded the 1:1 adducts - 4-oxopentyl formate (III) and 4-oxopentyl acetate (IV), respectively, together with the 1:2 telomers - 7-formyloxy-4-formyloxymethyl-2-heptanone (V) and 7-acetoxy-4-acetoxymethyl-2-heptanone (VI).The initial radiation yields are: G(III) = 200.8, G(IV) = 211.3, G(V) = 39.5, G(VI) = 37.9.Base-catalyzed transesterification of oxopentyl alkanoates III and IV afforded 5-hydroxy-2-pentanone (XIV), the same reaction of dialkylalkanoates VI and VII gave 5-hydroxy-4-hydroxymethyl-2-heptanone (XV).

CIDNP observations of the polarized signals from products of radical reactions in solutions of neat butane-2,3-dione in perfluorocyclohexane and perfluorodecalin, and in solutions with added radical scavenger or hydrogen donor, are consistent with three primary processes.There are symmetric (probably) and unsymmetric fragmentation and hydrogen-abstraction by triplet butane-2,3-dione from the starting material, and each yields free radicals.In all solutions the mechanisms of ensuing reactions are suggested.In the presence of CCl4 and CCl3Br pair substitution effects dominate the CIDNP behaviour.When high concentrations of propan-2-ol are present evidence is given for reaction of the excited singlet state of the parent molecule.
