A reciprocal-activation strategy for allylic sulfination with unactivated allylicalcohols was developed. In this reaction, the hydrogen bond interaction between allylicalcohols and sulfinic acids allowed for reciprocal activation, which enabled a dehydrative cross-coupling process to occur under mild reaction conditions. This reaction worked in an environmentally friendly manner, yielding water as

distinct protocols for the preparation of allylsulfones via Pd(II)-catalyzed allylicC−H activation. While the former protocol consists of a direct Pd(II)-catalyzed oxidative C−Hallylicsulfonylation in the presence of sulfinate anions, the latter involves a sequential one-pot Pd(II)-catalyzed C−Hallylic acetoxylation followed by a Pd(0)-catalyzed sulfonylation.
