Organometallic Complex Synthesis and Catalysis

The choice of the metal determines the redox chemical degradation of monovalent Group 13 metal amides containing a 1,8-diaminonaphthalene derivative as a difunctional amido ligand. Compound 1 reacts with InCl by a selective disproportionation to yield a dinuclear InII–InII complex (the In–In bond length of 2.7237(6) Å is the shortest measured so far). In contrast, the intramolecular redox reaction of 1 with TlCl leads to the oxidative coupling of two naphthalene units to generate the tetra-N-functionalized perylene derivative 2.
