Abstract
Diaryl sulfoxides undergo unusually rapid ligand-exchange reaction upon treatment with organolithium reagents at-95 OC. Optically pure phenyl p-tolyl sulfoxide (4b) reacted with organolithium reagents at the range from-20 to-95" C to give facile ligand-exchange and disproportionation products, ie, diphenyl sulfoxide (7), recovered 4b, and di-ptolyl sulfoxide (8) in a statistical ratio of 1: 21 in quantitative yields, and the recovered 4b wm completely ...
