Abstract
Compounds of the general formula: <FORM:0965424/C1/1> where R1, R2, R3 and R4 represent phenyl groups, R5 and R6 are the same and represent chlorine or phenyl, are prepared by heating triphosphonitrilic chloride or a phenyl substituted derivative containing fewer phenyl groups than the final product, with benzene in the liquid phase in the presence of a Friedel Crafts catalyst until a compound of the above formula is obtained. 2,21-4, 41-tetraphenyl-6,61-dichlorotriphosphonitrile may be produced by heating triphosphonitrilic chloride or 2,21-diphenyl-4,41-6,61-tetrachlorophosphonitril with benzene in the liquid phase at 50-120 DEG C., e.g. 80-100 DEG C., in the presence of a Friedel Crafts catalyst. Alternatively, the mixture may be heated under reflux for several weeks and the product recovered by fractional crystallisation or by chromatography. 2,21-4,41-6,61-hexaphenyltriphosphonitrile may be produced by heating triphosphonitrilic chloride, 2,21-diphenyl-4,41-6,61-tetrachloro triphosphonitrile, or 2,21-4,41-tetraphenyl-6, 61-dichlorotriphosphonitrile with benzene in the liquid phase and a Friedel Crafts catalyst at 120-180 DEG C., e.g. 150-160 DEG C. The preferred Friedel Crafts catalyst is aluminium chloride.
