Abstract
By bridging tetrahydroxy-1,10-phenanthrolines 9 by ditosylates 10 or d iiodides 11 concave 1,10-phenanthrolines 1 were synthesized. Their con cave 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.
