摘要：

The direct reduction of 1,2-bis[(2,6-dimethylphenyl)imino]acenaphthene (dmp-bian (1)) with gallium metal in toluene affords the solvent-free bis-ligand complex [(dmp-bian)(2)Ga] (2), in which two diimine ligands are in different oxidation states (radical-anionic and dianionic). The addition of phenylacethylene to the Ga-N-C moiety of the dianionic ligand of compound 2 gives the complex [(dmp-bian)Ga(HC=CPh)(dmp-bian)] (3), in which new Ga-C and C-C bonds are formed. The reaction of 2 with hex-1-yne produces the gallium dialkynyl complex [(dmp-bian)Ga(C C-Bu)(2)] (4), with the metal atom bonded to the dmp-bian radical anion. Paramagnetic compounds 2-4 were characterized by ESR spectroscopy and X-ray diffraction. The known compound dmp-bian was structurally characterized for the first time.
