The synthesis of water soluble pyrazolone derivatives dyes was achieved. The pyrazolidin-3,5-dione 5a,b and pyrazolin-5-one 3a,b and 4a,b units were selected as the key building block to prepare the glycoconjugated H-chromophore 6a–d, 7a,b, azo 8a–d, 9a,b and bisazo 10a–d, 11a,b dyes pyrazolone derivatives based. The water solubility values show that these derivatives require a minimum percentage weight
实现了水溶性吡唑啉酮衍生物染料的合成。的吡唑烷-3,5-二酮5A,b和吡唑啉-5-酮3A,b和图4a,b单位被选择作为关键构建块以制备糖缀H-生色6A - d,图7a,b,偶氮8A - d,9a,b和双偶氮10a – d,11a,b染料以吡唑啉酮衍生物为主。水溶性值表明这些衍生物需要最小百分数的缩水甘油部分重量百分比为水溶性,并且1 H和13 C数据证实了吡唑啉酮衍生物染料以其OH互变异构体形式存在的趋势。
