The reduction of benzophenone by lithium alkoxides gives rise to benzophenone ketyl which disappears in a first-order fashion and whose first-order rate constant is approximately equal to the pseudo-first-order rate constant for the formation of the product, benzhydrol.

โฆ Synopsis
Summaly: The stereochemical results of the reduction of cyclic ketones with alkoxyaluminium dichlorides do not conform to the conventional polar cyclic mechanism and may be explained by a single electron transfer mechanism.

Swmnurz~: EPR evidence supporting a single electron transfer mechanism in the reduction of secondary and tertiary alcohols to hydrocarbons with LiAlH4 is presented.
It has been demonstrated by means of spectroscopic studies involving cyclizable alkyl halides that lithium dimethylcuprate can react with organic halides by a single electron transfer pathway. The reaction of lithium diorganocuprates (LiCuR2) with alkyl halides is of major synthetic imp0rtance.l
