Structural Aspects

The addition of either lithium dimethylamide or lithium diethylamide to a tetrahydrofuran (THF) solution of 1,3-dicyclohexylcarbodiimide yielded THF adducts of lithium 2,2-dimethyl-1,3-dicyclohexylguandidinate (1) and lithium 2,2-diethyl-1,3-dicyclohexylguandidinate (2), respectively. One equivalent of either 1 or 2 was subsequently reacted with one equivalent of Group 11 halide (CuCl, AgBr, and AuCl) to generate oligonuclear complexes with the general formula {M[CyNC(NR2)NCy]}n where M, R, and n are respectively Cu, CH3, 2 (3); Cu, CH2CH3, 2 (4); Ag, CH3, 3 (5); Ag, CH2CH3, 3 (6); Au, CH3, 2 (7); and Au, CH2CH3, 2 (8). Compounds 1–8 were characterized by single-crystal X-ray diffraction. The bulk powders for all complexes were found to be in agreement with the crystal structures based on elemental analyses, Fourier transform infrared spectroscopy, and 1H, 13C, and 7Li NMR studies. The unique structural aspects of this family of Group 11 complexes are highlighted.

2-Chlorobenzo[c]cinnoline has been found to yield 4-dimethylaminobenzo[c]-cinnoline and 2,4,7-tris(dimethylamino)benzo[c]cinnoline on reaction with lithium dimethylamide. The same products are formed (although in a different ratio) from benzo[c]cinnoline and lithium dimethylamide. 4-Dimethylaminobenzo[c]cinnoline gives the 2,4,7-tris(dimethylamino) compound in low yield with lithium dimethyl-amide; but 2-dimethylaminobenzo [c]cinnoline appears to be completely unreactive. 4-Diethylaminobenzo[c]cinnoline is formed in the interaction of benzo[c]cinnoline and lithium diethylamide.
