Abstract

Trialkyl phosphates are inexpensive and stable at room temperature, under air, and are easy to handle. Mild, straightforward and powerful methods for nucleophilic alkylation of various N-, O-, C- and S-nucleophiles using readily available trialkyl phosphates proceed smoothly in excellent yields. Stereoselective transfer of secondary alkyl groups have also been achieved with inversion of configuration.
