Wittig reaction is a highly versatile method for forming alkenes from carbonyl derivatives. 2 An example of utilizing Wittig reaction is shown in Scheme 1: oxidation of R, β-unsaturated alcohols (I), 3 in which the CH bonds at the R-position of the hydroxyl group are “activated” by an adjacent π-bond, and subsequent Wittig reaction of the resulting R, β-unsaturated aldehydes (II) gives the corresponding diene derivatives (III). This type of procedure is ...
