| Abstract: | Reaction of Adipic Acid Diamide with Phosphorus Pentachloride The reaction of adipamide (I) with phosphorus pentachloride in a solvent leads to (Cl3P?NCCl2CCl2CH2)2 (II). The stages of the reaction are: 1. chlorination of the keto and methylen groups 2. formation of the ? N?PCl3 group. This result is a supplement of the existing conception about the course of the reaction of carboxylic acid amides with phosphorus pentachloride. The reaction of (I) with PCl5 without any solvent has been reproduced and the course of reaction has also been investigated. This reaction gives mainly NC(CH2)4CN. The resulting product of a careful hydrolysis of (II) is (Cl2OPN?CClCl2CH2)2. A total hydrolysis gives back (I). |
