selenium in THF, and afforded homoleptic alkalineearthmetal complexes of composition [M(THF)2Ph2P(Se)N(CHPh2)}2] (M = Ca (7), Sr (8), Ba (9)). The metal complexes 7–9 can also be obtained via salt metathesis route where the alkali metal phosphinoselenoic amides of composition [(THF)2M′Ph2P(Se)N(CHPh2)}2] (M′ = Na (5) and K (6)) were reacted with respective metal diiodides in THF at ambient temperature

1-H. The metal complexes 5–7 can also be prepared via a salt metathesis route, where the alkali-metal salts 3 and 4 were reacted with the respective metal diiodides in THF at ambient temperature. The molecular structures of 1-H and 2–7 have been established by X-ray diffraction analyses, and from the solid-state structures of 3–7, it was confirmed that, in all of the compounds, the metal ions are chelated

The reaction between phosphinamines [Ph2PNH(CHPh2)] (1), [Ph2PNH(CPh3)] (2) [Ph2PNH(CMe3)] (3), [Ph2PNH(2,6-Me2C6H3)] (4), and [Ph2PNH(2,6-(Pr2C6H3)-Pr-i)] (5) with BH3.SMe2 yields corresponding adduct [Ph2P(BH3)NH(CHPh2)] (1a), [Ph2P(BH3)NH(CPh3)] (2a), [Ph2P(BH3)NH(CMe3)] (3a), [Ph2P(BH3)NH(2,6-Me2C6H3)] (4a), and [Ph2P(BH3)NH(2,6-(Pr2C6H3)-Pr-i)] (5a) respectively. The solid state structures of all the compounds were established by single crystal X-ray diffraction analysis and in the solid state, all the compounds reveal that the phosphorus atom is preferably coordinated to the boron atom. Density functional theory (DFT) based electronic structure calculations were carried out taking various model phosphinamines to react with borane to establish the fact that the basicity of nitrogen atom adjacent to phosphorus in phosphinamines is reduced and thereby least preferred for coordination with borane.

elemental sulfur, corresponding sulfur compounds [Ph2P(S)NH(CHPh2)] (5) and [Ph 2P(S)NHCPh3] (6) are obtained. Further reactions of 4-6 with sodium bis(trimethylsilyl)amide in THF solution afforded corresponding sodium salts of molecular formula [(THF)2Na(Ph2P(O) NCPh3)}2] (8), [(THF)2Na(Ph 2P(S)NCHPh2)}2] (7) and [(THF) 2Na(Ph2P(S)NCPh3)}(THF)Na(Ph 2P(S)NCPh3)}] (9) and all the sodium complexes 7-9 are
