Abstract
The course of carboxyl group exchange in the thermal decomposition of a mixture of disodium adipate and pimelate has been studied using ^14^Cβlabelled compounds. The exchange data obtained from the residual acide and ketone formed point to two different incorporation processes. This phenomenon can be well interpreted by presuming the presence of a malonta type intermediate formed in the decomposition process.
