Abstract:

Barbier reactions in aqueous media are mainly performed with allylic halides and carbonyl substrates. This paper presents new a methodology for allylation of ionic substrates in aqueous such as diazonium salts. Getting the first product of allylation as well as of alkylation with halides saturated. Some allylbenzenes are obtained from sassafras oil extraction. However the propenylbenzene is not obtained from natural sources. During the studies on the allylation of diazoniun salts in water, the propenylbenzene was obtained as a major product in good yields. Due to the good result, we examined the applicability of the method to other saturated halides and different anilines.
