An FeCl3-mediated regio- and stereoselective Friedel–Crafts-type arylation of α-hydroxy phosphonates with unactivatedarenes has been developed in which the unstable allylphosphonate cations generated are stabilized by extended conjugation. The approach provides a simple, efficient and economic approach to highly demanding stereoselective γ-aryl-substituted vinylphosphonates and dialkyl (diarylmethyl)phosphonates
