Organic Polarography Donald J. Pietrzyk Department of Chemistry, University of Iowa, Iowa City, Iowa 52242
This review surveys articles described in Chemical A b stracts, Analytical Abstracts, Electroanalytical Abstracts, Chemical Titles, and readily available journals ending November 30, 1973. This period has seen a continued growth in the use of polarography and related electrochemical techniques to follow chemical reactions and to supplement other physical and spectral measurements for purposes of characterization. Interest in applications toward biochemical and pharmaceutical problems has also increased. There also appears to be renewed interest in utilizing polarographic and related electrochemical data to predict and follow organoelectrochemical synthesis. In this review the symbols cv, dc, ac, and op are used to identify cyclic voltammetry, direct current polarography, alternating current polarography, and oscillographic polarography, respectively. Also, no attempt was made to list all organic polarographic references. GENERAL REVIEWS Several general type reference books have been published. These deal with adsorption (222, 348), reactions in nonaqueous solvents ( 7 3 0 , electrode kinetics (2080), use of computers (744), role of acidity, free radicals, and of the double layer (2216), a general survey (488),and with biological compounds ( 2 227). Papers presented a t meetings have been published (153, 2195). Considerable interest in electrochemical synthesis and the use of polarography to predict the conditions or to follow the progress of the electrolysis has appeared. Several excellent books in this area have recently become available (53, 350, 2203). General polarographic reviews including organic polarography were compiled (100, 287, 334, 2260). Other reviews survey pulse polarography (551),op (244),and electrode processes (452). The stereochemistry of electrochemical reductions (351), role of free radicals (558), feasibility of using polarography to study monomer reactivity and polymer reaction kinetics (95), redox potentials for aromatic compounds (960), and kinetics and mechanisms of electrode processes leading to polymerization (230) have been reviewed. Surveys covering electrochemistry of P, As, Sb, S, and C onium salts and quaternary N salts (585), monoand dihalogen compounds ( E O ) , the determination of carbonyls after condensation with o-phenylenediamine (2245), the ECE mechanism and the effect of pH (2233), and cv data for oxidation of formic acid a t noble electrodes (266) were made. The EE and ECE mechanisms were computer-calculated and the calculations tested by the oxidation of 5,10-dihydro-5,10-dimethylphenazine and by the reduction of methylviologen and anthraquinone in MeCN (409). A survey of cathode ray and ac data were reported for 20 different nitro compounds (explosives) (447). Prediction of reduction potentials by SCF and HMO methods for fused aromatic hydrocarbons (358) and correlations between E1 2 for unsaturated hydrocarbons and energies of lowest vacant MO (734) were reviewed. Organic oxidation potentials and ionization potentials for 68 different organic compounds were correlated and used for predictions (765). Correlations between Ell2 for pDCeH4A, where D and A are electron donor and acceptor groups, and electronic spectra transitions were possible ( 704).

Low temperature techniques (>- 130 "C) and their applications were reviewed in detail and tested with several systems (2136, 2137). A general survey of the effect of nonaqueous solvents on E1,2 was made (600). The properties and purification of DMF (550) and DMSO (595) for voltammetric studies were reviewed. The use of carbon graphite electrodes 29), Hg, Pt, and C electrodes (310), and rotating ring-dis electrode (785) were reviewed. Surveys on the measurement of sorption of H and organic compounds on Pt (2022) and the use of CHzClz solvent with Pt, Ag, and DME (228) were made. The influence of the composition of C paste electrodes in the presence of surfactants was studied by cv (802) while methods of preparation, resurfacing methods, surface and static charge, adsorption, acidity, potential range, and scanning procedure and their effects on the use of glassy carbon and pyrolytic graphite electrodes in cv studies (847) were reviewed. Identification and study of the surfaces of different kinds of C and coal were described (255, 300,375). Several different surfactants were investigated as maxima suppressors (726), and a new electrochemisorption effect was suggested and tested with several systems (708). Streaming effects in polarographic maxima were described (69).

In the period since our preparation of the last Chromatography review for this Fundamental Reviews issue, chromatography has remained a very widely used analytical technique, with over 8000 publications on all aspects of chromatography appearing in the world literature. This review covers the literature of liquid column chromatography, paper chromatography, and thin layer chromatography (excluding ion exchange, which is reviewed separately elsewhere in this issue). The authors have attempted to select the most important publications abstracted in Chemical Abstracts between December 20, 1971, and December 3, 1973, and when possible, papers were selected which were published in journals readily accessible to American scientists. In order to conserve space and prevent possible overlap with coverage in the Analytical Applications Reviews published by this Journal in alternate years, the extensive second section on “Applications of Chromatography’’ ar-
ranged according to compound types, which has traditionally appeared in this review, has been eliminated. Some selected applications of the various chromatographic methods are still mentioned below, however, under the appropriate headings. During the past two years, the American Chemical Society sponsored short courses on modern liquid chromatography and maintaining and troubleshooting chromatographic systems.
