By bridging tetrahydroxy-1,10-phenanthrolines 9 by ditosylates 10 or diiodides 11 concave 1,10-phenanthrolines 1 were synthesized.Their concave shape was proven by X-ray analyses of 1a and 1c, their basicities were determined by photometric titrations.Compounds 1a-g are active in the base-catalyzed addition of alcohols to ketenes and form stable metal ion complexes with transition metal salts. - Key Words: Macrocycles / Broensted plot / Catalysis, base / Basicity / Transition metal complexes
