摘要: The first molecular compound with all five pnictogens was obtained by a multi-step reaction. Lithiation of the (bisamido)diazadiarsetidine (tBuNAs)2 (tBuNH)2 in aliphatic solvents leads to dimeric metallated species [(tBuNAs)2 (tBuNLi)2 ]2 (12 ). Upon reactions AsCl3 , SbCl3 and BiCl3 polycyclic compounds (tBuN)2 ]PnCl (Pn=As (2), Sb (3), Bi (4)) can be obtained. Conversion 2-4 [tBu2 SbP(tBu)Li(OEt2 )]2 remarkable interpnictogens ]PnP(tBu)SbtBu2 (5), (6), (7)), whereby 7 is example molecule containing Group 15 elements. adjacent AsNBiPSb-chains surprisingly stable does not show high sensibility against light as labile Bi-P bond might suggest.
