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).
