Aluminium-containing ring systems and N-heterocycle formation via nitrile insertions into Al–N bonds

Abstract

Reactions of Me₃Al with 1,2-diaminobenzene [1,2- (H₂N)₂C₆H₄] or anthranilic acid, [1,2-(H₂N)(HO₂- C)C₆H₄], followed by treatment with acetonitrile, afford tetranuclear and hexanuclear aluminium-containing ring systems; a single crystal X-ray structure on the hexametallic product reveals the construction of quinazoline ligands arising via insertion of acetonitrile into Al–N bonds.
