Synthesis and reactivity of Al(Et)q′2 (q′=2-methyl-8-quinolinolato) and crystal structures of [Al(Et)2q]2 and Alq′2q (q=8-quinolinolato)

A crystal structure of a dimeric aluminum complex ([Al(Et)2(q)]2, q=8-quinolinolato) (1) obtained by reaction of AlEt3 with 8-quinolinol has been determined by X-ray crystallography. Reaction of AlEt3 with 2-methyl-8-quinolinol gave a new reactive complex ( (q′=2-methyl-8-qinolinolato) (2)) in good yield. Reaction of 2 with 8-quinolinol provided Alq′2q (3) and the crystal structure of 3 was determined.
