Synthesis of New Schiff Bases Containing Thiophene Moiety
摘要
Seven new Schiff bases, which are 4,4,4-trifluo-ro- 1- ( 2- thienyl ) - 1- butanone- 3-Z, Z = - thiosemicarbazone ( a );-thiocarbohydrazone ( b ) ,-benzoic hydrazone ( c ), -( o-hydroxyphenyl) imine (d) ,-nicotinic hydrazone (e) ,-salicylichydrazone (f), and -(p-fluoro-m-chlorophenyl) imine (g),have been synthesized by reaction of 4, 4, 4-trifluoro-1-(2-thienyl)-1, 3-butanedione (TFTBD) with corresponding hy-drazides or anilines, acetic acid or p-toluence sulfonic acid as catalyst, and characterized by Elemental analysis, IR, UV-Vis,1H NMR and MS. The MS spectra confirmed that the-C3=O condensed with primary amino group. Tauto-merism of the compounds is discussed.
