Reaction is a base-catalyzed C-C bond-forming reaction between
nitroalkanes and aldehydes or ketones. It is similar to the
Aldol Addition, and also referred to
as the Nitro Aldol Reaction.
protons are available (i.e. when R = H), the products tend to eliminate
water to give nitroalkenes. Therefore, only small amounts of base should
be used if the isolation of the β-hydroxy nitro-compounds is desired.
