Novel 1,2-dicarba-closo-dodecaborane(12) derivatives of selenium

Lithiation of 1,2-dicarba-closo-dodecaborane(12) (1) followed by insertion of selenium into both C-Li bonds leads to the 1,2-diselenolato-1,2-dicarba- closo-dodecaborane(12) dianion (3), which is converted by oxidative coupling into the cyclic eight-membered bis(diselane) 4 with annellated carborane moieties. Oxidative addition of 4 to ethenebis(triphenylphosphane)platinum(0) gives the bis(triphenylphosphane)platinum(II) complex 7, which contains a chelating 1,2-diselenolato-1,2-dicarba-closo-dodecaborane(12) ligand, by symmetric cleavage of the eight-membered ring in 4 and displacement of ethene. The molecular structures of 4 and 7 were determined by X-ray analysis. The solution-state structures of the new compounds are supported by multinuclear NMR data (1H, 11B, 13C, 29Si, 31P, 77Se, 195Pt). Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

1,3,2-Diselenaphospholanes with an anellated dicarba-closo-dodecaborane(12) unit

The reaction of the 1,2-diselenido-1,2-dicarba-closo-dodecaborane dianion (1) with dichloro(phenyl)phosphane affords the 1,3,2-diselenaphospholane (2) containing an anellated dicarba-closo-docecaborane(12) unit. The phospholane 2 was oxidised by reactions with the elements to the sulfide 3 and the selenide 4, and partial hydrolysis gave a selenophosphonic acid derivative 5 along with the bis(diselane) 6 and decomposition. The reaction of 2 with (ethene) bis(triphenylphosphane)platinum(0) displaces ethene and is accompanied by oxidative addition and rearrangement into the bis(triphenylphosphane) platinum(II) complex 9, in which the chelating unit is linked to platinum via Pt-Se and Pt-P(Se) bonds, a rare example of a metallophosphane selenide. The molecular structures of 2 and 3 were determined by X-ray analysis. The solution-state structures of the new compounds follow from consistent multinuclear magnetic resonance data (1H, 11B, 13C, 31P, 77Se, 195Pt NMR).
