4-Chlorocarbostyrils , , , , with methoxy substituents in 6, 7, or 6,7-position react with potassium cyanide in a p-toluenesulfinate mediated reaction either to the highly fluorescent and stable 2-oxoquinoline-3,4-dicarbonitriles , , , or at slightly lower temperatures to 4-monocarbonitriles , , . 4-Chlorocarbostyril and lithium p-toluenesulfinate gave pure 4-toluenesulfonylquinolone , which reacted
4-氯咔啉 , , , , 在6、7或6,7位的甲氧基取代基与 对甲苯磺酸酯介导的对高荧光和稳定的2-氧代喹啉-3,4-二腈的反应中的氰化钾, , , 或在较低的温度下生成4-单腈 , , 。4-氯卡巴斯蒂利 和 对甲苯磺酸锂得到纯的4-甲苯磺酰基喹诺酮与氰化钾反应生成单腈 或二腈 ,取决于反应条件。4-三氟甲基喹诺酮类 和 由合适的甲氧基苯胺和4,4,4-三氟乙酰乙酸制备用于荧光比较的样品。
