Abstract
Ruthenafuran and osmafuran monocationic complexes [Ru([14]aneS4)(C∧O)]+ or [M(bpy)2(C∧O)]+ (C∧O = anionic bidentate chelate [C(OR)CHC(Ph)-O]-; [14]aneS4 = 1,4,8,11-tetrathiacyclotetradecane; M = Ru, Os; bpy = 2,2′-bipyridine) have been prepared from reactions between phenyl-ynone HC-C(CO)Ph and [Ru([14]aneS4)Cl2] or [M(bpy)2Cl2] in alcoholic solvents ROH. The formation of metal-vinylidene intermediate, followed by nucleophilic attack by RO-, and carbonyl group coordination to the metal center are believed to be the key steps in the formation of these metallafurans. The nature of the anionic C∧O ligand was investigated by electrochemical, spectroscopic, and theoretical means.
