A.novel and convenient protocol for synthesis of alpha-haloacrylates starting from phosphonium ylide and aldedyde or alcohol was described. Halodimethylsulfonium halide was used for the first time in halogenation of phosphonium ylide. Good yield as well as a high Z/E ratio were shown in representative cases, and an umpolung dimethyl sulfide-ylide species might be involved as an intermediate.

Pentacarbonyliron promotes addition of alpha-halocarboxylic acid esters at the carbonyl group of benzaldehyde and its para-substituted analogs. The substituent in the benzene ring strongly affects the process.
