Advances in Physical Organic Chemistry provides the chemical community with authoritative and critical assessments of the many aspects of physical organic chemistry. The field is a rapidly developing one, with results and methodologies finding application from biology to solid-state physics. Those interested in the relationship between the structure and function of organic compounds, including physical and theoretical chemists as well as organic and bioorganic chemists. Since his first appointment at Bath in , he has taught physical organic and computational chemistry to all years of the Chemistry programmes and is currently a Director of Studies. His research uses computational modelling and simulation as tools to aid the interpretation of experimental observations, and he has published on a broad range of topics from atmospheric chemistry to enzyme mechanisms. He has many years experience in experimental studies that are focused on understanding mechanism and reactivity in organic chemistry.
A general view of the medium effects on ionic reactions involves the solvent effect, ion pairing, formation of aggregates and structured environment. This review covers recent computational studies evidencing the presence of glycosyl cations as real intermediates in several glycosylation reactions. Optical purity op and enantiomeric excess ee become equal when either heterochiral dimerization constant is twice that of homochiral dimerization constant or specific rotations of monomer and dimer are equal. This critical short review focuses on some key features which determine successful enantioselective catalysed multicomponent reactions MCRs and are typically underappreciated in the literature. Investigation on the dynamic processes of 1- C 5 H 5 Si Me 3 in its Diels—Alder addition showed that Si Me 3 migration is the dominant factor and hydrogen shifts are negligible.

NMR Spectroscopy differs favorably from other physical methods of investigation IR and UV spectroscopy in that in some cases it makes it possible to detect directly the formation of intermediate products of chemical reactions ions, reaction complexes, solvates, etc. However, it should be noted that the conditions under which the NMR spectra of intermediate products are recorded often differ from the reaction conditions. In these cases some care must be exercised in comparing spectroscopic and chemical data. Despite these stipulations, the use of the NMR method often makes it possible to obtain quite unique data on the structure of intermediate products, making it possible to avoid the need of resorting to various hypotheses, often of a very speculative nature, to explain the mechanism of a process.

Physical organic chemistry — the study of the interplay between structure and reactivity in organic molecules — underpins organic chemistry, which cannot be imagined as a subject without knowledge of mechanism and reactivity. Novel experimental techniques combined with the revolution in computational chemistry give new impetus to physical organic chemistry and contribute to its continuing importance, which is reflected in the large number of international meetings in physical organic chemistry in the past two years.

Physical organic chemistry , a term coined by Louis Hammett in , refers to a discipline of organic chemistry that focuses on the relationship between chemical structures and reactivity , in particular, applying experimental tools of physical chemistry to the study of organic molecules. Specific focal points of study include the rates of organic reactions , the relative chemical stabilities of the starting materials, reactive intermediates , transition states , and products of chemical reactions , and non-covalent aspects of solvation and molecular interactions that influence chemical reactivity.
