Four betaines derived from imidazo[4,5-a], imidazo[5,4-a] and thiazolo[5,4-a]acridine have been prepared in a six step procedure starting from 2-chlorobenzimidazoles and benzothiazoles. The 1H and 13C nmr has been used to characterize the compounds, particularly the orientation of the step leading to the formation of the acridinone ring. The uv-visible spectra of one betaine (wave numbers v in cm−1)
从咪唑并[4,5衍生四甜菜碱一个],咪唑并[5,4-一个]和噻唑并[5,4-一个]吖已经从2- chlorobenzimidazoles和苯并噻唑开始的6个步骤过程中被制备。的1 H和13 C NMR被用于表征化合物中,步骤导致吖啶酮环的形成特别的方位。一个甜菜碱的紫外-可见光谱(波数v在cm -1中)显示出与Reichardt的E T参数呈线性关系,并且对溶剂效应具有很高的敏感性。
