Lewis basicity and affinity scales: data and measurement
Laurence, Christian
Gal, Jean-François
The Lewis concept of acids and bases is discussed in every general, organic and inorganic chemistry textbook. This is usually just a descriptive treatment,as it is not possible to devise a single numerical scale suitable for all occasions. However quantitative Lewis acid-base chemistry can be developed by compiling reaction-specific basicity scales which can be used in specific branches of chemistry and biochemistry. Lewis Basicity and Affinity Scales: Data and Measurement brings together for the first time a comprehensive range of Lewis basicity/affinity data in one volume. This collection of data will enable experimental chemists to better understand and predict the numerous chemical, physical and biological properties that depend upon Lewis basicity. Chemometricians will be able to construct many kinds of data matrices from the Lewis basicity scales of this book. In addition, measured experimental basicities and affinities are essential to computational chemists for the validation, calibration and establishment of reliable computational methods for quantifying and explaining intermolecular forces and the chemical bond. More than 2400 equilibrium constants of acid-base reactions, about 1500 complexation enthalpies, and nearly 2000 infrared and ultraviolet shifts upon complexation are gathered togetherin 23 thermodynamic and spectroscopic scales of basicity and/or affinity. Foreach scale, the definition, the method of measurement, an exhaustive database, and a critical discussion are given. All the data have been critically examined; some have been re-measured; literature gaps have been filled by original measurements; and each scale has been made homogeneous. Topics covered include: Lewis basicity and affinity measurements: definitions and context. the DonorNumber or SbCl5 affinity scale. the BF3 affinity scale. thermodynamic and spectroscopic scales of hydrogen-bond basicity. thermodynamic and spectroscopic scales of halogen-bond basicity. gas-phase cation basicity and affinity scales.the measurement of Lewis basicity and affinity in the laboratory Lewis Basicity and Affinity Scales: Data and Measurement is an essential single-source desktop reference for research scientists, engineers, and students in academia, research institutes and industry, in all areas of chemistry from fundamental toapplied research.
