摘要: The synthesis and structural characterization of the first [1.1]chromarenophanes [1.1]molybdarenophanes are described. A salt-metathesis reaction [2-(Me2NCH2)C6H4]AlCl2 with freshly prepared [Cr(LiC6H5)2]·TMEDA (TMEDA = N,N,N′,N′-tetramethylethylenediamine) resulted in dialumina[1.1]chromarenophane [{2-(Me2NCH2)C6H4}Al(η6-C6H5)2Cr]2 (2a). poor solubility 2a organic solvents prompted us to synthesize new intramolecularly coordinated aluminum- gallium dichlorides [5-tBu-2-(Me2NCH2)C6H3]ECl2 [E Al (3a), Ga (3b)] which phenyl group was equipped a tert-butyl group. Salt-metathesis reactions 3a 3b, respectively, [M(LiC6H5)2]·TMEDA (M Cr, Mo) four [1.1]metallarenophanes general type [{5-tBu-2-(Me2NCH2)C6H3}E(η6-C6H5)2M]2 Al, M Cr (4a); E Ga, (4b); Mo (5a); (5b)]. 2a, 4a,b, 5a,b have been structurally characterized by single-crystal analysis [2a·1/2C6H12: C48H56...
