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).
