Silica bromide as heterogeneous reagent is prepared from the reaction of silica gel with PBr3 as a nonhydroscopic, filterable, cheap, and stable yellowish powder that can be stored for months. The results show that the silica bromide is a suitable and efficient reagent for conversion of alcohols to alkyl bromides under mild conditions at room temperature. The easy availability of this reagent makes this simple procedure attractive and a practical alternative to the existing methods.

Keywords: Alkyl bromides, bromination, heterogeneous reagent, silica bromide, polynucleotide, reactive substances, malodorous, polypeptide, intrapolymeric, phosphorus.
