Reactions of 1,3,2-diselenaphospholanes with lewis acids: Borane and (pentamethylcyclopentadienyl)rhodium and -iridium dichloride

2-R-1,3,2-Diselenaphospholanes (R = iPr, Ph) with an annelated 1,2-dicarba-closo-dodecaborane(12) unit were treated with Lewis acids such as borane reagents (BH3 in THF, and BH3-SMe2) as well as Cp?-rhodium and -iridium dichloride (Cp? = pentamethylcyclopentadienyl). In all cases, the adduct formation in the beginning was followed by ring expansion through insertion of the borane or Cp?MCl2 into one of the P-Se bonds accompanied by transfer of a hydrido or chlorido ligand to phosphorus. Finally, the P-R unit was displaced from the ring to give the exchange products, in which the boron or the metal had become part of the five-membered rings. The reactions were monitored by NMR spectroscopy (1H, 11B, 13C, 31P, and 77Se). The proposed reaction sequences were found to be in agreement with calculated [B3LYP/6-311+G(d,p), LANL2DZ (Rh, Ir) level of theory] relative energies of optimized gas-phase structures of the various products. The novel molecular structure of the preferred insertion product with M = Ir, R = iPr was determined by X-ray analysis. Borane reagents as well as Cp?MCl2 (Cp? = pentamethylcyclopentadienyl; M = Rh, Ir) react with 1,3,2-diselenaphospholanes by the formation of adducts, followed by ring insertion, and finally by exchange.
