Abstract
Ratios of the yields of addition and reduction products for the reactions of butylmagnesium chloride with diisopropyl ketone, methyl 2‐methylpropanoate, and isopropyl 2‐methylpropanoate in toluene were determined at different THF, diethyl ether, and tert‐butyl methyl ether contents in the Grignard reagent. Replacement of the alkoxy group in the ester leads to strikingly different results for very small additions of donors. The results are discussed in terms of the solvation of the species in the reaction mixture.

## Abstract The reactivity in the normal Grignard addition reaction is greatly reduced when the ketone is branched in the α‐position. Alkylation in β‐position has only slight effect and in the γ‐position there is no effect at all.
