Abstract
Tris (4-aminophenyl)thiophosphate (TPTA) was synthesized from p-acetamindo phenol and phosphorus thiochloride through esterification and hydrolysis. Then Tris(4-maleoylaminophenyl)thiophosphate(TPTM) was synthesized from TPTA and maleic anhydride by amidation with the overall yield of 76.5%. IR, MS and NMR spectra were used to confirm the structure of TPTM and key intermediates. The ultraviolet-visible spectrum of TPTM was studied and there were two absorption peaks at 204.5 nm and 280.0 nm.
