Problems and exercisesReaction of Organometallic Compounds with Nitriles
1. From nitrile to ketone
Give the products of: a) propanenitrile with phenylmagnesium bromide and then H3O+; b) benzonitrile with tert-butyllithium and then H3O+.
2. Why is no tertiary alcohol formed?
With esters, Grignard reagents give tertiary alcohols. Why does the reaction with nitriles stop at the ketone?
