Allylzinc Bromide

[18925-10-5] C3H5BrZn (MW 186.39) InChI = 1S/C3H5.BrH.Zn/c1-3-2;;/h3H,1-2H2;1H;/q;;+1/p-1 InChIKey = UZNJLSDYFXAQJJ-UHFFFAOYSA-M (reagent used as a nucleophile in additions to carbonyl groups, imines, nitriles, alkenes, alkynes, and cross coupling reactions) Preparative Methods: usually preformed or formed in situ from allyl bromide and activated zinc dust. Zinc dust can be activated by treatment successively with 5 mol % of 1,2-dibromoethane and 1 mol % of TMSCl.1a Handling, Storage, and Precautions: allylzinc bromide should be prepared prior to use and can only be stored at 0 °C for a few days. Standardization of allylzinc bromide solution is best performed through GC analysis of its hydrolysis and iodolysis products.1a
