Among possible asymmetrically substituted phthalocyanines, ABAB derivatives remain rare. Their selective synthesis is based on the use of trichloroisoindolenines, so far remaining tedious to obtain. An optimized synthesis of 1,3,3-trichloroisoindolenine 1 and 1,3,3,6,7-pentachloroisoindolenine 2 is reported. An original crystallization method based on crystal growth by sublimation was eminently suitable regarding the air-sensitivity of these derivatives and allowed their thorough crystallographic characterization.
在可能存在的不对称取代酞菁中,ABAB 衍生物仍然很少见。它们的选择性合成基于三氯异吲哚啉的使用,但至今仍难以获得。本文报告了 1,3,3-三氯异吲哚啉 1 和 1,3,3,6,7-五氯异吲哚啉 2 的优化合成方法。基于升华晶体生长的独创结晶方法非常适合这些衍生物对空气的敏感性,并可对其进行全面的晶体学表征。
