Several hitherto unreported pentacoordinated triarylphosphorus, -arsenic and -antimony diamides, Ar3M(NR2)2 (Ar=phenyl, p-tolyl; HNR2=succinimide, phthalimide, imidazole, benzimidazole, rhodanine, tetrahydrocarbazole, isatin and benzotriazole) have been synthesized by metathetical reactions under mild conditions.The products have been characterised on the basis of analytical, IR, conductance and molecular weight data.The non-ionic nature of the compounds has been established by conductance and molecular weight measurements.M-N bonds (M=As and Sb) are cleaved in preference to M-C bonds by IBr, Br2, HgBr2 and TeCl4.However, these amides remain unaffected in the presence of MeOH.In contrast to its reaction with Sb-N bonds, CS2 gets inserted between As-N bonds.Preparation of representative tetraphenylstibonium amides Ph4SbNR2 (NR2=succinimide and phthalimide) is also reported.
