Scalable Wolff–Kishner Reductions in Extreme Process …

A safe and scalable continuous flow strategy for Wolff–Kishner reductions that employs methanol as the solvent has been developed. The use of low-cost hydrazine as the reducing agent in coination with a caustic base provides an atom-efficient, environmentally friendly method for the deoxygenation of aldehydes and ketones to alkanes. Because of the required harsh and corrosive reaction
