Grignard Reaction Lab Report

Secondary alcohols are produced by reacting a Grignard reagent with an aldehyde To create a tertiary alcohol the Grignard reagent must be reacted with a ketone 1 This is the type of reaction that takes place in the experimental portion of this report The reaction forms triphenylmethanol

Alcohol synthesis by 1 2

A highly efficient Zn-catalyzed alkylation of ketones and aldimines with Grignard reagents via trialkylzinc(II) ate complexes minimizes problems with the use of only Grignard reagents which leads to reduction and aldol side products and the yield of desired alkylation products could be improved

$begingroup$ Good answer I'd like to add a point to be considered: The initial electron transfer is usually slightly endothermic In the initiation process you will usually need to add some energy - the warmth of the hand might do (depending on the used halid) After the reaction started the formation of the Grignard is exotherm hence providing enough energy to overcome the activation

The Grignard Reaction

The Grignard Reaction The Grignard reaction is a simple acyl addition reaction between a nucleophilic organomagnesium reagent (a Grignard reagent) and an electrophilic carbonyl It is synthetically a very useful reaction as it is one of few that form a carbon-carbon bond Grignard reagents are prepared by reacting alkyl halides with magnesium
