Photolysis of (2,4,6-Tri-t-butylphenyl)bis(trimethylsilyl)phosphine

The photolysis of (2,4,6-tri-t-butylphenyl)bis(trimethylsilyl)phosphine in benzene gave products suggesting homolytic P-C bond cleavage followed by rearrangement and coupling.

Remote steric effects on the disproportionation / recombination ratio of cumyl radicals

The disproportionation / combination ratio in the reaction between two 3,5-di-tert-butylcumyl radicals, generated by thermolysis of the corresponding diazene, is 0.21 +/- 0.03 at 60 deg C in benzene.This is much larger than the value of 0.06 found for the unsubstituted cumyl radicals.It is suggested that the tert-butyl groups hinder the formation of a parallel association complex, which has been proposed to account for the much smaller amount of disproportionation in the reaction between benzylic radicals as compared with alkyl radicals.
