Preparation of only ketones
1.From acyl chloride : In this we make use of dialkyl cadmium ,then we react with RCOCL. For preparation we take grignard reagent :
Lets prepare acetophenone by this method :
2.From nitriles : In this we make use of grignard reagent and nitriles as shown in reaction :
In a similar manner, we can prepare acetophenone by taking grignard reagent as phenyl magnesium bromide and methyl cyanide.
