Piperylene sulfone was investigated as a recyclable dimethyl sulfide (DMSO) substitute for copper-catalyzedroom temperature aerobic alcohol oxidation. Under the optimal conditions, various primary alcohols couldbe selectively converted into aldehydes in excellent yields with exceptionally high turnover frequency (over31 h-1). The catalytic system also shows good compatibility with heteroatom-containing (S and N) substrates.Most importantly, the new developed catalytic system could also be recycled and reused for three runs withonly slight loss of catalytic activity.
