Macrocyclic chemistry: Part I. Synthesis, characterization and alkali metal stability constants of a new bis(phosphotriester) macrobicyclic polyether cryptand; Part II. Characterization of a new valence-averaged mixed-valence di-ruthenium complex, and of

The study of macrocyclic ligands for complexation of alkali metals (macrobicyclic polyether cryptands) and transition metals (tetraaza macrocycles) is reported. The synthesis of a new bis(phosphotriester) macrobicyclic polyether cryptand, O = P (O(CH;Also reported are the synthesis and characterization of (1) a new mixed-valence bimetallic ruthenium complex, Ru;The ruthenium dimer 3 was formed by oxidative dehydrogenation of Ru(C;The keto complex 4 was formed in high yields (...
