In contrast to the formation of C−O and C−N bonds it was only recently that the selective C−Sbondformation by means of transition metal complexes moved more into the center of research. This is somewhat surprising given the fact that the sulfur atom in a functional group can possess different oxygenation levels which correspond to different chemical properties and reaction portfolios. Herein we wish
easy. The use of sulfinate salts as nucleophiles in substitutions is frequently accompanied by side reactions such as π‐bond migration, β‐elimination, and so on. Herein we present a preparatively simple way to synthesize a variety of different aryl or alkyl allyl sulfones starting from readily accessible allylic carbonates. By employing aryl or alkyl α‐sulfonyl succinimides as sulfinate synthons, mild
