Abstract
The co-formation of diarylalkane by-product in the bromoalkylation of an aromatic compound with an ether corresponding to the formula R--O--R', wherein R is an .alpha.-chloroalkyl group containing at least two carbons and R' is R or alkyl, is minimized by conducting the reaction with agitation in the absence of a cosolvent and in the presence of both hydrogen sulfate and hydrogen bromide.
