Abstract

Abstract Alk-2-enesulfonyl chlorides 1–4 were synthesized by the BCl 3-promoted ene reaction of alkenes with SO 2. These sulfonyl chlorides were then used as electrophilic partners in iron-catalyzed desulfinylative cross-coupling reactions with different Grignard reagents (aromatic, aliphatic, andheteroaromatic). The reaction can be catalyzed with even 2 mol-% of the simple iron salt Fe (acac) 3. The regioselectivity of these allylations was ...
