Abstract

A mixture of ethyl bromoacetate and 1-octene was treated with triethylborane in water at ambient temperature to provide ethyl 4-bromodecanoate in good yield. The bromine atom- transfer radical addition in benzene was not satisfactory. The addition proceeded smoothly in polar solvents such as DMF and DMSO, protic solvents such as 2, 2, 2-trifluoroethanol and 1, 1, 1, 3, 3, 3-hexafluoro-2-propanol, and aqueous media. Ab initio calculations were ...
