Application

Allyl bromide can be used:
  • As a starting material to prepare allylaluminum and allylgallium sesquibromides.
  • As a precursor in the synthesis of allyl ketones by reacting with substituted nitriles under Barbier-type reaction conditions.
  • As a starting material in the synthesis of 2-allyl-1(E),3(E)-dienyl sulfoxides by reacting with 1,2-allenylic sulfoxides using Pd catalyst.
  • In the indium catalyzed addition reactions of N-tert-butylsulfinyl aldimines to yield N-tert-butylsulfinylamine chiral building blocks.

A methylene-interrupted C18 keto-acetylenic fatty ester (methyl 12-oxo-9-octadecynoate) was obtained from methyl ricinoleate by bromination-dehydrobromination followed by oxidation. Reaction of methyl 12-oxo-9-octadecynoate with bis(benzonitrile) palladium(II) chloride, allyl bromide, or methyl-allyl bromide furnished methyl 8-[5-hexyl-3-allyl-furan-2-yl]-octanoate (1, 56%) or methyl 8-15-hexyl-3-(2-methyl-allyl)-furan-2-yl]-octanoate (2
