Water-soluble Metal Complexes and Catalysts, IV.- 2,2'-Bipyridine-5-sulfonic Acid: Synthesis, Purification, Derivatives and Metal Complexes

The synthesis of 2,2'-bipyridine-5-sulfonic acid (1a) is achieved by mercury(II)-catalyzed sulfonation of 2,2'-bipyridine in oleum (30percent SO3) in 10-50-g amounts.The crude product is purified by extraction of 1a as tetra(n-butyl)ammonium salt into dichloromethane and re-extraction of the free acid with conc. hydrobromic acid.Melting of 1a together with potassium hydroxide gives 5-hydroxy-2,2'-bipyridine (2).The salts 1b-d (Na+, +, +) and sulfonamides 1f-h (tert-butyl, benzyl, 2-pyridylmethyl) of the acid 1a are ligands of different solubility.The coordination chemistry of these N,N-chelating ligands is studied.The compounds 4-14 of chromium, molybdenum, tungsten, manganese, rhenium, and osmium containing carbonyl or oxo ligands are prepared as examples of chelate complexes with metals in low and high oxidation states.The solubility of the complexes is mostly determined by the cations: Sodium salts are usually soluble in water and/or in short-chained alcohols.Tetra-n-butylammonium and tetraphenylphosphonium salts and the sulfonamides are soluble in polar organic solvents.On the other hand, the distribution of charge has an influence on solubility.Increased polarity of the anion, caused by high oxidation states of the metals, decreases the solubility of the complex in organic solvents.

We report the syntheses of 2,2'-bipyridine-4,4'-disulphonic acid (H2bp-4,4'-ds) and 2,2'-bipyridine-5-sulphonic acid (Hbp-5-s), and several ruthenium(II) complexes derived therefrom, including 4-, 2- (bipy=2,2'-bipyridine), , and - and their 2,2'-bipyridine-4,4'-dicarboxylic acid (H2bpdc) analogues, viz. 4-, 2-, and .Some novel thioalkyl derivatives of 2,2'-bipyridine, including 4,4'-di(methylthio)-2,2'-bipyridine, 4,4'-di(ethylthio)-2,2'-bipyridine, and 4,4',6,6'-tetra(methylthio)-2,2'-bipyridine, were also prepared and characterised during the course of this investigation.The luminescent states of the complexes 4-, 2-, 4-, 2-, and were studied using variable-temperature lifetime measurements.Studies of the quenching of 2+>*, >*, 2->*, and 4->* by 1,1'-dimethyl-4,4'-bipyridinium bromide (methyl viologen) in aqueous solution as a function of ionic strength have demonstrated that the effects of charge in these electron-transfer reactions can be understood in terms of conventional theories of ionic reactions whilst, at the same time, confirming the effective charges of the ruthenium(II) complex ions.The rate constants for the quenching of 4->* and 2->* by copper(II) ions in neutral aqueous solution show unusual (non-Arrhenius) temperature dependences.A novel kinetic scheme involving parallel inner- and outer-sphere quenching mechanisms has been proposed to account for the observed behaviour.The luminescence decay of >* in the presence of aqueous copper(II) ions at pH 3.5 is non-exponential.This is interpreted in terms of a combination of static and dynamic quenching effects.
