Reactions of BeEt2 with
S(NSiMe3)2 and carbodiimides RNCNR yielded homoleptic
bisdiimidosulfinate [EtS(NSiMe3)2]2Be (1) and amidinate
complexes [EtC(NAr)2]2Be (Ar = 2,6-i-Pr2-C6H3 2, SiMe3 3). In addition, the heteroleptic amidinate [t-BuC(NAr)2]BeEt (4) and β-diketiminate [HC(CMeNAr′)2]Be(i-Bu) (6) (Ar′ =
2,4,6-Me3C6H2) complexes were obtained
by alkane elimination reactions of BeEt2 with t-BuC(NSiMe3)N(H)SiMe3 and Be(i-Bu)2 with β-diketimine [Ar′N(H)C(Me)CHC(Me)NAr′],
respectively. In addition, 4 was found to react with
dry oxygen with formation of the corresponding alkoxide [t-BuC(NAr)2]BeOEt (5). 1–6 were characterized by multinuclear NMR (1H, 9Be, 13C) and IR spectroscopy as
well as by single-crystal X-ray diffraction (1, 2, 4, 5, 6).
