Full TextAbstract
Abstract1,2-Ethanediylbis(triphenylphosphonium) ditribromidewas quantitatively prepared and used for the bromination of anilines and phenols in the presence of a mixtured solvents system (DCM/MeOH 2:1) and also under solvent free conditions.This new ionic liquid has advantages over similar brominating agents in terms of short reaction time, simple work-up, regioselectivity and high yields. Single crystal X-ray analysis of title salt, revealed that the bistriphenylphosphoniumcation is organized around an inversion center located at the center of the -CH2-CH2- bridge and the two triphenylphosphine segments are anti with respect to one another. All the tribromide anions adopt a linear geometry with different Br-Br-Br bond angles foreachanion.
