Acid-induced reactions of 1-cyclopropyl-1-ferrocenyl-ethanols and -methanols
Abstract
The reactions of some 1-cyclopropyl-1-ferrocenyl-ethanols and -methanols under mild acidic conditions are described. The stereospecific ring opening observed in some cases is rationalized in terms of a preferred conformation of the bisected carbocation. The influence of substituents upon the reaction is discussed.
