Highly Efficient Darzens Reactions Mediated by Phosphazene Bases under Mild Conditions
The highly basic and poorly nucleophilic phosphazene base P(1)‐t‐Bu promotes the Darzens condensation of α‐halo esters with aromatic aldehydes affording α,β‐epoxy esters in nearly quantitative yields under mild conditions and in short reaction times. The more basic P(4)‐t‐Bu phosphazene was found us...
