Element-Element Bonds, IV. Molecular and Crystal Structure of Tetramethyldiphosphane and -diarsane

The molecular and crystal structures of the isotypic compounds tetramethyldiphosphane 1 and -diarsane 2 have been determined by single crystal X-ray diffraction (monoclinic; C2/m; Z = 2; 1/2: -155/-144 deg C; a = 540.6(2)/555.8(2); b = 1131.0(6)/1136.7(6); c = 602.5(2)/612.8(2) pm; β = 97.31(3)/95.24(3) deg; P-P 221.2(1)/As-As 242.9(1) pm.In accordance with the crystallographically imposed symmetry 2/m, the molecules adopt antiperiplanar conformation.Their crystal structures are closely related to those of the homologues tetamethyldistibane 3 and -dibismuthane 4.As found for the latter compounds, the E-E units (E = P, As) are also aligned in linear chains, but the intermolecular E...E contacts (P...P 381/As...As 370 pm) do not allow any extended interaction between molecules, which otherwise would result in thermochromic effects. - Keywords: Tetramethyldiphosphane, Tetramethyldiarsane, Conformation, Molecular Structure, Crystal Structure

NMR studies of the reactions of Me2AsH with Me2AsNMe2 and Me2AsNMe2·BH3: Synthetic routes to Me2AsAsMe2

Me2AsH reacts irreversibly with Me2AsNMe2 and Me2AsNMe2·BH3 to give good yields of Me2AsAsMe2. The nitrogen-containing product is Me2NH or Me2NH·BH3, respectively. These reactions have been followed by using multinuclear (1H, 11B, and 13C) NMR spectroscopy to elucidate the respective reaction mechanisms. Although the Me2AsH/Me2AsNMe2 reaction proceeds faster initially, the overall rate of reaction is slower than that for the Me2AsH/Me2AsNMe2·BH3 reaction. This is a consequence of the presence of inhibiting exchange reactions in the Me2AsH/Me2AsNMe2 system that are absent when Me2AsNMe2 and Me2NH are bound to BH3 in the Me2AsH/Me2AsNMe2·BH3 reaction. A detailed NMR study of the exchange reactions involving the >AsNNH, >AsAsAsH, and >AsNAsAs2AsAsMe2.
