Chlorine adds to activated cyano groups to give substituted N-chloroformimidoyl chlorides, as was reported by several authors. 2,3,4.
cyanuric chloride. Conditions which accelerate the trimerization of the cyanogen chloride, such as presence of Lewis acids, HCl. HzO, and a ratio of Cl2 : CICN < 1:1, should therefore be avoided. Compound ( I ) , which is a colorless liquid having b.p. 87 "C, can be distilled under normal pressure.
Die Reaktion von Benzylidenmalononitrilen mit Cyanthioacetamid (1) ergibt je nach den Reaktionsbedingungen entweder Thiopyrane oder Pyridine. Die Strukturen der Reaktionsprodukte wurden mittels l3C-NMR aufgeklart. In the last decade we have been involved in a program aiming at efficient syntheses o
