WebThe reaction takes place in two parts. The first step is the nucleophiic addition of the carbonyl group to form an imine. The second step is the reduction of the imine to an amine using an reducing agent. A reducing agent commonly used for this reaction is sodium cyanoborohydride (NaBH 3 CN). WebThe compounds containing a carbonyl group (the -C=O group) are called carbonyl compounds. The carbonyl group, C=O, is probably the most important functional group in organic chemistry. These compounds are an integral part of organic chemistry and their primary members are called aldehydes, ketones, and carboxylic acids.

Secondary carbonyl

In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes, ketones and carboxylic acids), as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carb… WebThe leaving group in ester reduction is the RO – alkoxy group while for amides, the carbonyl oxygen is converted into a leaving group and then eliminated.
