Abstract

Di-tert-butylmagnesium has been found to be a reactive, yet non-nucleophilic and non-reductive, carbon-centred base for the deprotonation of a series of ketones. This reagent demonstrates equally high reactivity when used as either the pre-formed reagent, or in a more accessible one-pot protocol from the parent Grignard reagent, and offers improved atom-efficiency over more traditionally employed bases.
