| Abstract: | Nitration between 9,9-bis(4-hydroxyphenyl)xanthene(1)with 20； aqueous HNO3 15 ~ 20 ℃ for 3 h yielded 9,9-bis(3-nitro-4-hydroxyphenyl)xanthene(2)in 86. 5； yield,which was further converted to 9,9-bis(3-amino-4-hydroxyphenyl)xanthene(3)in 92. 7； yield by reduction with hydrogen in the presence of catalytic amount of Pd / C at 75 ~ 80 ℃ for 1 h in methanol solvent. The two-step overall yield of 3 was about 80. 2；(based on compound 1)and their structures of 2 and 3 were characterized by 1 H NMR,IR and elemental analysis tech-nique. |
