Again the product is the same whichever of the two reducing agents you use.

Reagent reduce carbonyl in methyl vinyl ketone. What reagent would be used to reduce an amide to an amine. Aldehydes and ketones can. Only iii o d. Initially the grignard reagent is added to the weinreb amide which further undergoes hydrolysis to furnish ketone.

Carboxylic acids esters and acid halides can be reduced to either aldehydes or a step further to primary alcohols depending on the strength of the reducing agent. Which reagent can be used to reduce an acid chloride to an aldehyde. A because the grignard reagent will react with the acid and be quenched. The enantioselectivity arises from the preference of the larger carbonyl substitutent for the pseudoequatorial position of the ring.

Why can t you use acidic conditions such as aqueous hydrochloric acid for the addition of a grignard reagent to a ketone. Which reagent would be used to reduce the carbonyl in methyl vinyl ketone. Only 1 o c. Reduction of a ketone leads to a secondary alcohol.

For example with propanone you get propan 2 ol. However alkyllithium reagents are less likely to reduce the ketone and may be used to synthesize substituted alcohols.
