  • Descrição: 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).
