  • Descrição: Reactions of aluminum metal with 3,6-di- tert -butyl- o -benzoquinone (3,6-Q) in various solvents gave aluminum tris- o -semiquinolate and catecholate. The metal catecholate underwent partial hydrolysis in the presence of water. The dimeric complex [(Cat)Al(OH)Bipy] 2 × 4C 2 H 4 Cl 2 (Cat is the 3,6-Q dianion and Bipy is 2,2-bipyridyne) with bridging OH groups was isolated and characterized by X-ray diffraction. A reaction of aluminum with o -quinone in the presence of molecular iodine yielded the dimeric catecholate iodide [(Cat) 2 Al(Et 2 O) 2 ]AlI 2 . The structure of the latter was confirmed by X-ray diffraction. An aluminum catecholato- o -semiquinolate complex was obtained by an exchange reaction between [(Cat) 2 Al(Et 2 O) 2 ]AlI 2 and thallium o -semiquinolate.
