文摘

Reactions of BeEt₂ with bis(diphenylphosphinimino)methanes H₂C[PPh₂NR]₂ yielded the first bis(diphenylphosphinimino)methanide and bis(diphenylphosphinimino)methanediide beryllium complexes [CH(PPh₂N-2,6-i-Pr₂C₆H₃)₂]BeEt (1), [C(PPh₂NSiMe₃)₂](BeEt)₂ (2), and [C(PPh₂NPh)₂](BeEt)₂ (3), respectively. 1–3 were characterized by multinuclear NMR and IR spectroscopy as well as single-crystal X-ray diffraction.
