2-(Chloromethyl)-3-tosylpropene (5) prepared directly from commercially available 3-chloro-2-(chloromethyl)propene reacts with a variety of heteronucleophiles and Grignard derivatives to afford allyl sulfones 7 and 8 respectively. It reacts also with electrophiles such as carbonyl compounds in the presence of zinc metal under Barbier conditions to give functionalized allyl sulfones of the type 12.
