摘要
从易得的原料出发,采用合理的步骤,合成出2种新型品成色剂3-苯基-6-甲基1H-吡唑并[5,1-C][1,2,4]三唑(Ⅱ)和3-十五烷基-6-甲基-1H-吡唑并[5,1-C][1,2,4]三唑(Ⅳ)。试验了Ⅱ与硫酰氯的反应,得到预期的7-氯衍生物(7-Cl-Ⅱ)。使Ⅳ和7-Cl-Ⅱ分别与CD-2反应制得相应的品染料,通过测定吸收光谱,表明光谱曲线接近理想吸收。
Phenyl-6-methyl-1H-pyrazo[5,1-C][1,2,4]triazole(Ⅱ)and 3-pentadecyl-6-methyl-1H-pyrazolo[5,1-C][1,2,4]triazole(Ⅳ)as a new type of magenta coupler have been synthesizedthrough a simply reasonable process from easily obtained raw material.7-Chloro-derivate of Ⅱ hasbeen prepared by the reaction of n with SOZC12. The spectral cure of maqenta dye obtained by the reaction of the 7-C1-Ⅱ(orⅡ)and Ⅳ with CD-2 is close to ideal absorption of color photographic system.
