The derivatization and fluorodensitometric determination of carboxylic acids (CA), imides and alcohols with 1-chloromethylbenz[c,d]indol-2(1H)-one (19, CMBI) have been studied. Out of a series of fluorescent fused lactams 9-11, 13-15 and 17, benzindolone 17 was selected and transformed via hydroxymethylbenzin-dolone 18 into CMBI 19. CMBI reacts with CA, diCA and alcohols respectively to yield strongly
研究了用1-氯甲基苯并[ c,d ]吲哚-2(1 H)-one(19,CMBI)衍生化和荧光密度法测定羧酸,酰亚胺和醇的方法。了一系列稠合的荧光内酰胺的的9-11,13-15和17,benzindolone 17被选择和转化通过hydroxymethylbenzin-dolone 18到CMBI 19.与CA,DICA和分别醇CMBI反应产生强荧光苯并〔C, d ]吲哚-1-基甲基酯20、21(BIM酯)和BIM醚22。苯巴比妥通过CMBI的作用转变为荧光1,3-bisBIM苯巴比妥25。对衍生化反应在荧光密度法测定CA,醇和酰亚胺上的适用性研究表明,可以通过BIM酯测定具有3个以上碳原子的CA下降到低皮孔范围。在使用醇和酰亚胺的情况下,结果并不令人满意。还介绍了所制备的苯并吲哚衍生物的红外光谱,紫外光谱,荧光光谱,核磁共振谱和质谱图。
