8,9,10,11-Tetrachloro-12H-isoindolo[2,1-a]perimidin-12-one (cas: 20749-68-2) belongs to indole derivatives. Indole could be stereoselectively alkylated with chiral cyclopentyl sulfone reagent. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.Related Products of 20749-68-2

Contribution of annelation to the thermal stability of some coloring materials was written by Matsuoka, Masaru;Ishisaka, Mikio;Kitao, Teijiro;Konishi, Kenzo. And the article was included in Nippon Kagaku Kaishi in 1972.Related Products of 20749-68-2 This article mentions the following:

Benzimidazoles, phthaloperinones, 3′-hydroxyquinophthalones, quinazolone-phthalones and their annellation derivatives were prepared by the reaction of substituted phthalic or 2,3-naphthalenedicarboxylic anhydride (I) with o-C6H4(NH2)2, 1,8-C10H6(NH2)2, 3-hydroxy-4-carboxyquinaldine, or 2-methyl-4-quinazolone. The fastness to sublimation for these compounds on polyester fiber and PVC [9002-86-2] sheet was tested. The thermal stability (thermogravimetric anal.) of the annelation derivatives prepared from I was better than that of the derivatives from phthalic anhydride. The annelation effect on color and light fastness of these coloring matters were also discussed. In the experiment, the researchers used many compounds, for example, 8,9,10,11-Tetrachloro-12H-isoindolo[2,1-a]perimidin-12-one (cas: 20749-68-2Related Products of 20749-68-2).

Adding equimol. amounts of 5,6-diaminoacenaphthene and the desired anhydride of an o-phthalic or naphthalic acid to glacial AcOH, refluxing 3-4 hrs., cooling, filtering, and washing with cold AcOH and H2O gave the following dyes (% yield, m.p., and color given): phthaloaceperinone (I), 62, 287掳, -; tetrachlorophthaloaceperinone (II), 68, 294-5掳 -; naphthaloaceperinone (III), 64, 230掳, light bordeaux; 4(5?)-benzoylnaphthaloaceperinone (IV), 90, 223-4掳, reddish violet. These aceperinones were more deeply colored than the corresponding perinones. The maximum absorbance of I and II was higher and shifted to longer 纬 than that of III. Kapron dyeings obtained with III and IV were more resistant to washing, crocking, and ironing, but less lightfast, than those obtained with the corresponding periones.
