Abstract

THERE have been several reports of carbon isotope effects during the decarboxylation of dibasic carboxylic acids such as malonic acid1. Similar effects would be expected in the radical reaction: The rate at which the radical R.14CO.O dissociates is expected to be less than that for the corresponding reaction of the radical R.12CO.O.
