A probe of Cieplak's proposal: effect of 2-axial substitution on reactivity in the LiAlH4 reduction of cyclohexanones
Abstract
The relative reactivities of cyclohexanones in which the 2-axial position is substituted by methyl or methoxy group in LiAlH4 reduction strongly support the Cieplak model which focuses on the importance of stabilisation of the transition state by antiperiplanar allylic bonds.
