RELATIVE ACTIVITIES OF TETRAHYDROFURFURAL ACETALS IN THE DETACHMENT OF A HYDROGEN ATOM BY tert-BUTOXYL RADICALS

Article abstract of DOI:10.1007/BF00506983

The activities of linear and cyclic acetals of tetrahydrofurfural in the reaction with tert-butoxyl radicals were studied.The k_a/k_d parameters, which are ratios of the rate constants for the accumulation of tert-butyl alcohol to the rate constants for the formation of acetone, are close to the parameters for 2-alkyl-substituted acetals.Linear acetals are less active than cyclic acetals, the activities of which increase on passing from 2-tetrahydrofurfuryl-1,3-dioxolane to its sulfur- and nitrogen-containing analogs.
