| Abstract: | A series of borane and monoiodoborane derivatives of bis(diphenylphosphino)alkanes. (C6H5)2P--- (CH2)n---P(C6H5)2 in which n has values of 2 through 4 has been synthesized. Only compounds with the formulae (C6H5)2P]2(CH2)n · (BH3)2 and (C6H5)2P]2CH2)n · BH2I were isolable, the latter being boronium iodides. The compounds were characterized by their melting points, elemental analyses, molar conductivities, infrared spectroscopy, and 1H and 11B nuclear magnetic resonance spectroscopy. The relationship between the length of the carbon chain and the 11B NMR chemical shift is discussed. |
