摘要：

Efficient bromination of polyaniline base to poly(2-bromoaniline)-bromide is successfully carried out using bromodimethylsulfonium bromide. Poly(2-bromoaniline)-bromide salt was obtained in a dry amorphous nature, having high conductivity (2.5 S/cm) with agglomerated spherical morphology. Poly(2-bromoaniline)bromide salt was proved to be a novel, efficient, reusable, cheaper and eco-friendly polymer-based solid acid catalyst in the reaction between aromatic amines and N-vinyl lactam under solvent-free conditions to provide 2-methyl-4-anilino-1,2,3,4-tetrahydroquinolines. These 2,4-disubstituted tetrahydroquinolines were synthesized with trans selectivity. (C) 2014 Elsevier B.V. All rights reserved.
