Significance

A manganese catalyst system is employed in the aminohalogenation of β-methyl-β-nitrostyrenes. Interestingly, the regioselectivity of the reaction is the opposite of comparable aminohalogenation processes, with the chlorine moiety on the α-carbon of the nitroalkane. The method is a new approach to generating halogenated quaternary stereocenters.
