One of the main tasks of physical organic chemistry is to study the mechanisms of chemical reactions by instrumental methods. The rapid development of various techniques and new spectroscopic methods in recent years has attracted attention to the investigation of elementary steps of reactions and the intermediates involved. In accordance with modern requirements, the description of reaction mechanisms should include the participation of relatively stable species. 

This review article summarizes the broad area of electroorganic synthesis, (selected electroorganic synthetic reactions, with a special emphasis on those that have been commercialized or investigated in pilot plants) and selected applications of electrochemical techniques for waste-water and effluent treatment. There are a number of modern textbooks and updated reviews [4-53] of electroorganic chemistry that include much more detail on organic reactions and their mechanisms than it is appropriate to discuss here.

Within last 15 years new application of isotope effects has been developed. Natural abundance precise NMR measurements of deuterium, 13C and sporadically 17O enable determination of isotope effects for all atoms within molecules. This is a new opportunity for organic and physical organic chemists probing the reaction mechanisms. Fast development of sensitivity of modern NMR spectrometers and continuously better access to them should encourage scientists to apply KIEs measured at natural abundance. 

Most evident to the modern biochemist, apart from the body of knowledge of the chemistry and metabolism of biological substances, is the extent to which he must draw from recent concepts of physical and organic chemistry, and in turn project into the vast field of biology. Thus in the organization of Comprehensive Biochemistry, the middle three sections. Chemistry of Biological Compounds, Biochemical Reaction Mechanisms, and Metabolism may be considered classical biochemistry, while the first and last sections provide selected material on the origins and projections of the subject.
