Bromination of Phenol and Anillin derivatives in Presence of [MdPd](Br3)2

Mono(6,7-dihydrodipyrido[1,2-a:2 ,1 -c]pyrazine-5,8-diium)hexabromide[MdPd].(Br3)2was quantitatively prepared and used for the bromination of anilines and phenols inthe presence of a mixed solvent system (e.g., Acetonitril or DCM/MeOH 2:1) and under solvent free conditions [1-2]. Also it has been done selective oxidation of Benzyl alcohols to their corresponding carbonyl compounds in presence of Mono (6,7-dihydrodipyrido[1,2-a:2 ,1 -c]pyrazine-5,8-diium) diperchlorate. This new ionic liquid has advantages over similar brominating agents in terms of short reaction time, simple workup, regioselectivity and high yields.
