5,1-a]isoindoles and a new type of tetrazoloisoindole based monomethinecyanines were isolated. Their structure was confirmed by X-ray diffraction analysis. A mechanism of the formation of these new dyes is proposed. This reaction permit to introduce easily various alkyl, aryl or heteroaryl substituents on the central methine carbon.
对1-甲基四唑并[5,1- a ]异吲哚与酰氯的酰化反应的研究产生了两个系列的衍生物。分离了5-酰基-1-甲基四唑[5,1- a ]异吲哚和一种新型的基于四唑异吲哚的单次甲基花菁。通过X射线衍射分析确认了它们的结构。提出了这些新染料的形成机理。该反应允许在中心次甲基碳上容易地引入各种烷基,芳基或杂芳基取代基。

An IR study of the 5-acyl tetrazoloisoindoles solvent sensitive bands permit to assign the bands associated to the valence mode of the C=O bond in the 1700-1500 cm(-1) area. This provides an explanation of the unusual stability of these newly synthesised compounds. Moreover, in air exposed solutions we observe the formation of unique degradation products. A mechanism for their formation and their probable structure was proposed with the help of IR spectroscopy. (C) 2003 Elsevier B.V. All rights reserved.
