Hexabromocyclododecane with enhanced gamma isomer content is produced by brominating cyclododecatriene in a liquid medium comprised of (1) at least 50 wt % of at least one liquid inert organic solvent other than 1,4-dioxane having a solubility in water of at least 1 wt % at 25° C., and (2) water in an amount of up to about 40 wt %, in the presence of (3) about 0.5 to about 30 wt % of bromide ion (Br-), each wt % being based on the total weight of the liquid portion of the liquid medium.
