Metal catalyst-free substitution of allylic and propargylic phosphates with diarylmethyl anions†
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.
