Pivalophenone

WebSolution-phase photolysis of pivalophenone (phenyl t-butyl ketone) gives radicals with a spin polarization showing complex time-evolution. It is suggested that the polarization may be due to a process involving two rates of separation of the initial radical pair. One is separation from a triplet pair; the other, sl WebMar 28, 2024 · Pivalophenone N–H imines bearing a series of para-substituents all participated in the alkenylation reaction to afford the desired products 3ba–ga in good yields. The reaction of m -methyl-substituted imine took place preferentially at the less hindered position to afford 3ha as the major isomer with a moderate regioselectivity of 3:1.
