“…The behavior of tetracyanoquinodimethan (165) and 2-benzhydryl-7,7,8,8tetracyanoquinodimethan (267) in acetonitrile was reported with the latter showing two well defined one-electron reversible waves. Polarographic data for dicyanomethylene -2,2,4,4-tetramethylcyclobutane and the bis derivative were determined in order to facilitate selection of conditions for radical formation in EPR studies (545).…”

HIS REVIEW covers articles which T have appeared in Chemical Abstracts and readily available journals during the two-year period ending November 1, 1965. As in the past, duplications and reinvestigations of previous work appear widely, and the tendency for authors to publish the same work in more than one journal has continued.This period has seen the publication of a special issue of Talanta honoring the 70th year for Professor Izaak If. Kolthoff (411). This issue is comprised entirely of invited contributions of his former students and associates and a list of Professor Kolthoff's past publications. Best wishes go to Professor Kolthoff for many more years of fruitful labor.Polarographic advances in Japan ( m 4 , 800, 801) and in Prague (429) were reviewed. The use of electron spin resonance spectrometry in evaluating electrode reactions in which free radicals are formed has continued t o grow (3, 25). Books dealing with "Polarography of Polymers'' (64) and "Organic Polarographic Analysis" (947) hare been published. Two books containing a listing of literature covering polarography through 1964 also became available (340,341 ) Yunierous reviews have appeared on the applications of polarography to pesticide analysis (98,224,226,524), lignin chemistry (627), cytostatically active compounds ($239, smoke analysis (700), proteins (114, 567,893), pharmaceuticals and drugs (1 74, 242, 249,329, 659,917), petroleum analysis (171 , 318,942), polymers (63), biocheniical analysis (661)) feed medicament analysis (9), clinical chemistry (104) , and enzyme activity (435). Other reviews have covered organic analysis (119,169,830,331) , organic polarography (496, 543, 583,773,805,897,914,946) and application to electrochemical synthesis (28.5) * Specialized polarographic reviews were concerned with alkaloids and their analysis (706), the effect of pH on halfwave potentials (176), utilization in assigning ring and chain structures and following the rate of tautomerism (344), polarography of enediols (log), substituted 3-phenyl-sydnones (767) , carbon disulfide and derivatives (639) and organic peroxides (269), the study of electron and proton transfer (6), the progress and problems in electrode kinetics (84) and the techniques for studying kinetics of oxidation (210).Reviews on adsorption of organic compounds at electrode surfaces (13, 218,443) and effect on reduction (493), a theoretical treatment of adsorption (136), and studies in adsorption isotherms (148) have appeared. Oscillographic and alternating current polarography were used to study the effects of anionic, cationic, and neutral surface active agents on polarographic analysis (337). Additional studies on adsorption are included under specific compounds.Studies in nonaqueous media have been reviewed (199,253,412). Other studies, however, mere concerned with the effects of different solvents on polarographic active compounds ($11, 71 9 ) .Work on the correlation of half-wave potentials with various constants continues. The relationship between halfwave potential...
