Abstract
Diary1 ant1 dialkyl Sulfoxides undergo facile phase-transfer-catalyzed (F'TC) deoxygenation with dichlorocarbene at 25 OC to afford excellent yields of sulfides. Comparisons of deoxygenation rates of dialkyl and diaryl sulfoxides suggest that steric acceleration occurs with the bulky sulfoxides while resonance interactions from aromatic rings retard the reduction. Less bulky sulfides also undergo the reverse reaction: addition of ...
