(from preface)Volume 26 includes 3 chapters. C. A. Ramsden reports heterocy-clic betaines derived from 6-membered heteroaromatic jewelry. those compounds were intensively studied over the last 10 years and feature no longer formerly been comprehensively reviewed. O. Meth-Cohn and B. Tarnowski summarize the chemistry of the thiocoumarins, a a little bit missed staff of heterocycles.
Advances in Inorganic Chemistry provides well timed and informative summaries of the present development in quite a few topic components inside inorganic chemistry, starting from bioinorganic to sturdy kingdom.
