The lsomerization of Olefins Part I. Base-Catalysed lsomerization of Olefins

Isomerization of olefinic and acetylenic compounds have received much attention during las few years both in their theoretical and in practical aspects. The methods used in isomerization of olefins (migration of the olefinic double bond) and related reactions are the subject of the this review; isomerizations involving rearrangement of the carbon skeleton are not considered. Part I deals with base-catalyzed isomerizations. Part II is concerned with isomerizations catalysed by acids, metal complexes, radicals, etc. The knowledge of the conditions under which isomerization of olefins occurs, is not only valuable for the conversion of olefins to their isomers, but is an important consideration when olefins are to be prepared by any other means. Under such conditions as here described an unwanted reaction product may be formed as a result of isomerization.
