  Reaktion von Bis(methylzink)-1,2-dipyridyl-1,2-bis(tert-butyldimethylsilylamido)ethan mit Triisopropylsilylphosphan und -arsan

  摘要：

  The reaction of bis(methylzinc)-1,2-dipyridyl-1,2bis(tert-butyldimethylsilylamido)ethane (1) with triisopropylsilylphosphane gives the three-nuclear complex [1,2-dipyridyl-1,2-bis(tert-butyldimethylsilyl amido)e thane] trizinc-bis(mu -triisopropylsilylphosphanediide) (2). Two zinc atoms show the coordination number of four whereas the third metal center is located between the two phosphorus atoms with a bent P-Zn-P-moiety. The reaction of 1 with triisopropylsilylarsane proceeds analoguesly, however, we were not able to isolate analytically pure [1,2-dipyridyl-1,2-bis (tert-butyldimethylsilylamido) ethane] trizinc-bis (mu -triisopropylsilylarsanediide) (3).

  The protonation of racemic (1S,2S)-bis(methylzinc) and (1R,2R)-bis(methylzinc) 1,2-bis((trialkylsilyl)amido)-1,2-dipyridylethane (2) with acetamide quantitatively yields racemic 1,2-bis((trialkylsilyl)amino)-1,2-dipyridylethane (3); the meso form 4 is not observed. Irradiation of 3 leads to an equilibrium mixture of all possible isomers, which have been detected by NMR spectroscopy. The crystal structures of 3 and 4 show elongated C-C bonds of the ethane backbone. Recrystallization of 3 from a water/acetone mixture resulted in precipitation of a water adduct of 3, which crystallizes in a chain structure with weak hydrogen bridges. The reaction of 2 with aniline gave bis(methylzinc) 1,2-bis(phenylamido)-1,2-dipyridylethane (5). Experiments with N-15-labeled aniline show that, however, the C-N, not the Si-N, bonds are cleaved.
