Diphenyl (4′-(Aryldiazenyl)biphenyl-4-ylamino)(pyridin-3-yl)methylphosphonates as Azo Disperse Dyes for Dyeing Polyester Fabrics
Diphenyl (4′-aminobiphenyl-4-ylamino)(pyridin-3-yl)methylphosphonate (1) was synthesized in 88% yield from reaction of pyridine-3-carboxaldehyde with benzidine and triphenylphosphite in the presence of titanium tetrachloride as a catalyst. Diazotization of 1 gave the corresponding diazonium salt 2 w...
