Herein, we reported a dual-catalytic platform for the allylation of amines and sulfonyl hydrazines with olefins to selectively access α-allylic amines and allylic sulfones in good yields by combining photoredox catalysis and cobaloxime catalysis. This strategy avoided the use of a stoichiometric amount of terminal oxidant and the use of pre-functionalized allylic precursors, representing a green and ideal atom- & step-economical process. Good substrate scope and gram-scale synthesis demonstrated the utility of this protocol. Mechanistic studies revealed that a radical process is probably involved in this reaction.

Addition products of arenesulfonyl chlorides to α-methylstyrene in the presence of catalytic amounts of copper(II) chloride and triethylamine hydrochloride underwent fast dehydrochlorination (according to Hofmann's rule) on heating in boiling acetonitrile to give the corresponding aryl 2-phenylallyl sulfones with high selectivity. This reaction underlay a one-pot procedure for the synthesis of new compounds that attract interest as potential biologically active substances, monomers, and cross-linking agents for polymeric materials from accessible starting compounds.
