Abstract:

The reaction of dimethyl-phosphine and -arsine with tetrakistrifluoromethyl-diphosphine and -diarsine gave the mixed fluoroalkyl-alkyl derivatives CF32P-PCH32, CF32As-PCH32, CF32P-AsCH32, and CF32As-AsCH32 containing P-P, As-P, and As-As bonds. The reactions appear to depend on the basic strength of the hydride since the fully fluorinated phosphino-arsine CF32P-AsCF32 was obtained from the action of bistrifluoromethylarsine on tetrakistrifluoromethyldiphosphine but the diarsine was not affected by bistrifluoromethylphosphine. The fully fluorinated phosphino-arsine, also obtained from the reaction of a mixture of bistrifluoromethyliodo-phosphine and -arsine with mercury, could not be isolated from the diphosphorus and diarsenic compounds and was characterised spectroscopically. Interesting features of the n.m.r. and mass spectra of the compounds are discussed. Author
