Synthesis, Characterization, and Reaction of Digermylenes

A series of digermylenes R(EGeL)(2) (L=CH[C(Me)N(Ar)](2), Ar=2,6-iPr(2)C(6)H(3); E=O, R=1,3-C6H4 (1), 1,4-C6H4 (2), Me2C(CH2)(2) (3); E=NH, R=1,4-C6H4 (4), 1,4-C6H10 (5); E=C(O)O, R=1,3-C6H4 (6)) were synthesized by the reactions of L ' Ge (L '=HC[C(CH2)N(Ar)]C(Me)N(Ar), Ar=2,6-iPr(2)C(6)H(3)) with selected diphenols, diol, diamines, and o-/m-phthalic acids, respectively. Treatment of digermylene 1,3-C6H4(OGeL)(2) (1) with sulfur, selenium and CuX (X=Cl, Br, I) led to the formation of 1,3-C6H4[OGe(S)L](2) (8), 1,3-C6H4[OGe(Se)L](2) (9), and (CuX)(2)[1,3-C6H4(OGeL)(2)](2) (X=Cl (10), Br (11), I (12)), respectively. The obtained products were characterized by melting point, elemental analysis, FT-IR, H-1 and C-13 NMR spectroscopy, and single-crystal X-ray diffraction.
