4,4′,5,5′-Tetrakis(guanidinyl) binaphthyl - Synthesis and Properties of Two Redox-Active Ligands and Oxidative C-C Coupling to Perylene Derivatives

We report the synthesis and properties of the new redox-active ligands 4,4',5,5'-tetrakis(tetramethylguanidinyl) binaphthyl and 4,4',5,5'-tetrakis(N, N'-dimethylethyleneguanidinyl) binaphthyl. The first dinuclear zinc complexes were prepared. Oxidative C-C coupling of these compounds leads to perylene derivatives.
