Abstract in another language
The use of 1,2-diselenolato-1,2-dicarba-closo-dodecaborane(12) dianions [1,2-(1,2-C2B10H10)Se2]2− prepared in situ as the dilithium salt may lead to irreproducible results. This is shown by the straightforward synthesis of silanes using the purified and isolated dianions, in contrast with previous less successful attempts. Thus, the reactions of the dianions with dichlorosilanes afford the five-membered diselenasila cycles containing the SiMe2 or the SiPh2 units, and with 1,2-dichloro-tetramethyldisilane the six-membered cycle containing the Si2Me4 unit. The latter was studied by X-ray diffraction, and all products were characterized by multinuclear magnetic resonance (1H, 13C, 29Si, 77Se NMR) in solution. Novel isotope effects were detected in 13C and 77Se NMR spectra. Exchange reactions of the five- and six-membered diselanasila cycles with chlorosilanes were studied.
