资源简介：
A combination of benzyl carbamate and N-chlorosuccinimide
was developed as a new system for aminohalogenation of β-nitrostyrenes
catalyzed by potassium carbonate in dichloromethane at room temperature.
The reaction tolerates a wide range of substituents on the β-nitrostyrene,
and proceeds smoothly in good-to-excellent chemical yields
(77-99%). The new system shows a high efficiency
and it markedly shortens the reaction time for aminochlorination. N,N-Dichlorobenzyl
carbamate was also found to be a highly efficient source of both
nitrogen and chlorine for the aminohalogenation reaction.
