Description of  Synthesis of Medium-Sized Cycloalkenes via Fused-Cyclobutenes (Springer Theses)

9819707862 rar This book explains the existence of the intermediate using two approaches: computational chemistry and coordination chemistry. In this book, the author has developed new methods for synthesizing medium-sized cycloalkenes by utilizing the 4-electrocyclic reaction of fused-cyclobutenes. The fundamental and most important strategy and feature of the work are as follows: first, cyclobutene is used as a readily available raw material with high-strain energy to generate more strained medium-sized cis,trans-cycloalkadiene molecules. Second, by judiciously selecting the reaction conditions, the short-lived intermediate (medium-sized cis,trans-cycloalkadiene) can be converted to medium-sized cis- or trans-cycloalkenes. For the former, the generation of the medium-sized cis,trans-cycloalkadiene intermediate is greatly affected by the substituent on the cyclobutene, and there are few examples of its generation confirmed at room temperature. Regarding the latter, the synthesis of Read more
