Synthesis and application of 2-styryl-6,7-dichlorothiazolo[4,5-b]-quinoxaline based fluorescent dyes: Part 3

A new efficient synthesis of 2-styryl-6,7-dichlorothiazolo[4,5-b]quinoxaline based fluorescent dyes was achieved by the condensation of 2-methyl-6,7-dichlorothiazolo[4,5-b]quinoxaline with selected 4-N,N-dialkylaminoarylaldehydes and heteroarylaldehydes in the presence of piperidine. The coloristic, fluorophoric, and dyeing properties of these dyes were studied.
