Abstract

Competitive kinetic experiments utilising free radical carbonylation chemistry provide a first estimate for the rate constant for 6-endo cyclization of the 6-aza-7-ethyl-5-hexenoyl radical of (4.8 ± 2.4) × 10 6 s-1 at 90° C in benzene, in good agreement with ONIOM-G3(MP2)-CC+COSMO-RS calculations (6.8 × 106 s -1).
