development of new approaches which smartly bypass the use of harsh reaction conditions and hazardous chemicals covers a pivotal role. In this research paper the synthesis, characterization, and application of novel libraries of triazine bis-quaternary ammonium salts, employed as coupling agents to produce amides is reported. Full characterization of the novelcompounds by 1H and 13CNMR, FT-IR spectroscopy

Syntheses of various symmetrically and non-symmetrically trisubstitutedtriazines are reported. Dynamic NMR (1H and 13C) experiments demonstrate that 2,4,6-tris(dialkylamino)-s-triazines show correlated rotations of the alkyl groups in the dialkylamino moieties. Unsymmetrical 2-chloro-, 2-alkoxy- and 2-aryloxy-4,6-bis(di-n-alkylamino)-s-triazines display two non-equivalent n-alkyl groups, due to the
