Process for the manufacture of 2-stilbenyl-1,2,3-triazoles which contain carboxyl groups, novel 2-stilbenyl-1,2,3-triazoles which contain carboxyl groups and the use thereof as fluorescent brighteners

摘要

Process for the manufacture of 2-stilbenyl-1,2,3-triazoles containing carboxyl groups by reacting a 2-tolyl-1,2,3-triazole with an anil in the presence of a strongly basic alkali compound in a strongly polar, neutral to basic organic solvent as well as novel 2-stilbenyl-1,2,3-triazoles containing carboxyl groups are described.
