Several classes of arylphosphorus acid amides have been tested in reactions with alkali metal solutions in liquid ammonia. The outcomes of such reactions depend on the structures of the starting materials. Generally, two processes-Birch reduction or cleavage of the P-aryl bond-can be operative. Diarylphosphinic amides tend to undergo double Birch reduction to afford bis(cyclohexadienyl)phosphinic amides. Copyright

Dibromophosphines, RPBr2, are obtained by reaction of tetrabromomethane with 7-substituted 7-phosphanorbornenes in toluene at ca. 100 °C. The phosphanorbornenes are obtained in situ by cycloaddition of N-phenylmaleimide with 1-substituted 3,4-d
Reactivity of X3P compounds with elemental sulfur, carbon disulfide or both, to yield X3PS, X3RCS2 or X3P.Sn.CS2 adducts

Kinetic constants k2 have been obtained for the reaction of sulfur with 25 PIII compounds in toluene or hexane. In the series PhnMe3-nP (n = 1-3) or PhnBu3-nP (n = 0-3), log k2 decreases linearly with Σχi (χi=Tolman's electronic parameter of each ligand on P), taken as a gauge for the donor strength of P. Dramatic deviations from additivity are observed for the series PhnP(OEt)3-n, PhnP(OEt)3-n, and BunP(OEt)3-n(n = 0-3); the deviation is smaller for PhnPCl3-n, and even smaller for PhnP(NEt2)3-n . The results are discussed in terms of P-coordination (PIV vs. PV), stability and geometry of the intermediate X3P.S8 or of the transition state leading to this adduct, emphasis being laid on the donor/acceptor character of the P site. A similar dependence on X governs the reactivity of X3P with S8, CS2 or both, to give X3PS, X3P.CS2 (binary red adduct) or X3P.Sn.CS2 (ternary yellow adduct) respectively; an explanation for this parallelism is proposed.
REACTIONS OF AMINOPHOSPHINES WITH ALKYL THIOCYANATES. 1,2-BISTETRACYANOETHANES AND N2-ALKYLDICYANOMETHYL-N1-(HEXAETHYLTRIAMINOPHOSPHORANYLIDENE)CYANOFORMAMIDINES

Reactions of hexaethyltriaminophosphine and tetraethyldiaminophenylphosphine with alkyl thiocyanates have been found to proceed in an unusual way and to give rise to the appropriate aminophosphine sulfides, alkyl cyanides, dialkyl sulfides and disulfides along with the formation of 1,2-bistetracyanoethanes and N2-alkyldicyanomethyl-N1-(hexaethyltriaminophosphoranylidene)cyanoformamidines.These reactions were assumed to take both a heterolytic and a homolytic course.X-Ray and mass spectral studies of the polycyanides obtained have been carried out. Key words: Aminophosphines; alkyl thiocyanates; 1,2-bis(phosphoranylideneamino)tetracyanoethanes; N2-alkyldicyanomethyl-N1-(phosphoranylidene)cyanoformamidines; Arbuzov reactions; homolytic pathways.
