Electrolytes for Li-ion transport – Review

Publisher Summary This chapter focuses that the field of intramolecular reactions is a mature area in which the merging of concepts from both physical organic chemistry and polymer chemistry leads to a unified treatment of cyclization rates and equilibria in terms of a few simple generalizations and theories. It is concerned with reaction rates, equilibria, and mechanisms of cyclization reactions of chain molecules. It discusses that parallel to the search for synthetic methods to make rings of all sizes, kinetic studies have appeared with the aim of providing insight into physical aspects of ring closure. A significant portion of the evidence available on the kinetics of intramolecular reactions falls in the domain of neighboring group participation. The term is sufficiently wide to encompass “all intramolecular reactions and all reactions that involve nonelectrostatic through-space interactions between groups in the same molecule.” However, the most common types of neighboring group participation involve nucleophilic participation either with or without anchimeric assistance and intramolecular acid and base catalysis. The chapter explores that intramolecular catalysis phenomena have attracted much attention, both from the experimental and theoretical points of view, not only on account of their inherent mechanistic interest, but also because they are believed to model the extraordinary efficiency of enzyme catalysis.
