Reactions of 5-(Perfluoroalkyl)Tetrazolates with Cyanogen, Nitrosyl, and Cyanuric Chlorides. (Reannouncement with New Availability Information).

摘要

Compounds with high nitrogen content, especially tetrazoles and their salts, are high-energy materials and may explode when exposed to mechanical, thermal, or electrical stimulation. Tetrazoles as well as their salts that contain the NF2 moiety are useful oxidizers when chemically combined with fuels such as anhydrous hydrazine. Sodium azideand hydrazoic acid may undergo 1,3-dipolar or HI type addition reactions. However, 1,3-dipolar addition is the most commonly observed mechanism in reactions with acetylene and nitriles. An exothermic reaction occurs between sodium azide and (difluoroamino) difluoroacetonitrile, NF2CF2CN (1), to give sodium 5-((difluoroamino) difluoromethyl)tetrazolate.
