Improved preparation of 5-chloro-1-phenyl-1H-tetrazole and other 5- chlorotetrazoles

Reaction of aryldichloroisocyanides 1a-e with sodium azide and a phase transfer agent has provided 5-chloro-1-aryl-1H-tetrazoles 2a-e in good yield. In particular, the widely-used intermediate, 5-chloro-1-phenyl-1H-tetrazole 2a, can be produced conveniently and safely in yields approaching 100%.

POLYFLUOROARYLCARBONIMIDOYL DICHLORIDES AND CHLORIDES. A NEW METHOD OF OBTAINING SUCH COMPOUNDS FROM POLYFLUOROAROMATIC AMINES AND COMPOUNDS OF THE CCl3R TYPE IN THE PRESENCE OF AlCl3

Reactions of some polyfluorinated amines of the benzene, diphenyl, naphtalene and pyridine series with CCl4 in the presence of AlCl3 have been investigated.A new method is proposed for producing polyfluoroarylcarbonimidoyl dichlorides ArfN=CCl2.The reaction is shown to be sufficiently general and applicable in the series of polychlorinated anilines and low-base anilines of the hydrocarbon series as well.The possibility of involving other compounds of the type CCl3R and other Lewis acids in the reaction has been studied.The factors influencing the course of the reaction and the mechanism of formation of polyfluoroarylcarbonimidoyl dichlorides are discussed.
