The ratio seems to be affected by the kinetic isotope effects on the CRCL and DRCY step. Similar kinetic isotope effects have been found to be responsible for the 52:48 ratio observed in the PET degenerate Cope rearrangement between 3,3,4,4-tetradeuterio-2,5-diphenyl-1,5-hexadiene and the corresponding 1,1,2,2-tetradeuterio derivative which proceeds in a cation radical cyclization-diradical cleavage mechanism.
