摘要：

Mono- and diazo compounds of 5-(2-nitrophenyl-azo-)2,2',4,4'-tetrahydroxybenzophenone and 5,5'-di(2-nitrophenyl-azo-)2,2',4,4'-tetrahydroxybenzophenone have been synthesized by the azo-coupling reaction of o-nitrobenzenediazonium chloride with 2,2',4,4'-tetrahydroxybenzophenone. Esterification of the mono-azo compound with acryloyl and methacryloyl chloride gave the monomeric acryloyloxy and methacryloyloxy azo-pigments in 57 and 59% yield. Reductive cyclization of the mono-azo compound gave a yellow product containing two types of ultra-violet absorbers, i.e. benzophenone and benzotriazole units. All compounds were characterized by their IR, UV, and H-1 NMR.
