The reduction of ethyl acetoacetate with sodium borohydride is show below. Explain why the product of the reaction does not have two alcohol functional groups.
Homework Answers
Simple answer to this question is that NaBH4 is mild reducing agent it only reduces aldehydes and ketones . Given compound is having both ester and ketone functional group so Use of NaBh4 only reduces keton part not the ester one. Instead if we have used LiAlH4 ( lithium aluminium hydride ) it reduces both ester as well as ketone because it is a powerful reducing agent .

EXPERIMENT SEVEN SODIUM BOROHYDRIDE REDUCTION OF ACETOPHENONE HOCH, DISCUSSION The reduction of an aldehyde or ketone with sodium borohydride is straight forward and usually affords a high yield of the alcohol. The usual procedure (and the one employed in this experiment) involves dissolving the borohydride in 95% ethanol and adding the carbonyl compound to this solution. To ensure complete reaction, an excess of sodium borohydride is used. The reaction between sodium...

We performed a synthesis of methyl diantilis lab. The first step
involved a Sodium Borohydride Reduction of
3-Ethoxy-4-hydroxybenzaldehyde (Ethylvanillin) shown below.
The next step of the experiment involved Etherification of
3-ethoxy-4-hydroxylbenzyl Alcohol using one of four alcohols
(methanol, ethanol, 1-propanol, or 2-propanol). The alcohol I used
was methanol. The reaction is predicted below.
