2-Bromo-1,3,5-triisopropylbenzene

2-Bromo-1,3,5-triisopropylbenzene is an ethylene acetal that is prepared by the catalyzed reaction of aryl chlorides and anhydrous zinc bromide in the presence of triethylamine. The selectivities of this method are high because it can produce mainly a single isomer. The stereoselectivity is also high because the reaction proceeds with the formation of only one stereoisomer. The mechanism for this reaction involves a nucleophilic substitution of the halogenated aryl chloride with the trialkylborane, which generates two different products. This product has been used in the synthesis of biphenyls and nitro compounds.
