Urea condenses readily with 1 or 2 molecules of bromal forming respectivelymonobromal urea (I), anddibromal urea (II) CBr3 . CH(OH). NH. CO. NH2 I CBr3 . CH(OH). NH. CO. NH. CH(OH). CBr3 II The condensation proceeds somewhat less readily than does the corresponding reaction with chloral. When, for example, the compounds are left in aqueous solution, monobromal urea only is formed, even when excess of the aldehyde is used. The monobromal urea thus produced condenses normally with a second molecule of bromal only when the two compounds are melted together and heated for a time at 100°.
