Henry








Common Conditions:


Beta-Nitro Alcohol

The reaction of a nitroalkane with an aldehyde or ketone in the presence of a base provides beta-nitro alcohols. A common side reaction is the dehydration of the beta-nitro alcohol to a nitroalkene.[1]





Nitroalkene

Nitroalkenes are often the desired product of a Henry reaction. This usually is achieved by using elevated reaction temperatures.
