Abstract

Substitution of secondary allylic phosphates with the anions derived from Ar₂CH₂ with BuLi or LDA proceeded regioselectively and stereoselectively without a metal catalyst, affording inversion products in good yield. Similarly, propargylic phosphates gave propargylic products selectively.
