Synthesis of styrene dibromide

Preparation of styrene dibromide

Alternative Names: (1,2-DIBROMOETHYL)BENZENE; 93-52-7; Dowspray 9; 1,2-Dibromo-1-phenylethane; Benzene, (1,2-dibromoethyl)-; 1,2-Dibromo(phenyl)ethane;

Preparation of styrene dibromide

Preparation of styrene dibromide

Styrene dibromide is obtained by slowly dropping a solution of 80 grams bromine dissolved 100 ml carbon tetrachloride into a solution of 52 g styrene dissolved in 50 ml carbon tetrachloride with vigorous stirring at —10 to —15° C; towards the end of the reaction the mixture is cooled in water or ice to prevent its premature solidification. After a short time, styrene dibromide is filtered off and dried in the air (yield 90-95 %). Styrene dibromide is pure enough for the most synthesis proposes, like preparation of phenylacetylene.

Chem. Ber., 89, 1786. 1956.

Styrene dibromide could be prepared by bromination styrene with a mild brominating agent – dioxane dibromide, C4H8O2 · Br2.

Preparation of styrene dibromide by bromination with dioxane dibromide

Preparation of styrene dibromide by bromination with dioxane dibromide

Gradually adding 25 g of dioxan dibromide to 10.4 g of styrene with cooling in running water and subsequently diluting the mixture with water affords 100% of styrene dibromide without any nuclear substitution.
