Reaction of phosphonyl radicals with substituted orthobenzoquinones

Reactions of α-Diketones ando-Quinones with Phosphorus Compounds

“…Treating diethyl phosphite with tert -butyl peroxide in toluene generates phosphonyl radical, which reacts with o -benzoquinones 4 (R 1 = R 3 = t -Bu, R 2 = R 4 = H; R 1 = R 4 = t -Bu, R 2 = R 3 = H; R 1 = t -Bu, R 2 = R 4 = H, R 3 = OMe; R 1 = t -Bu, R 2 = R 3 = H, R 4 = NO 2 ; R 1 = t -Bu, R 2 = R 4 = H, R 3 = CPh 3 ) to yield the corresponding phenoxy radicals 370 (ESR) …”
