Abstract

Easily reachable electron-poor/rich primary and secondary benzylic phosphates are suitably substrates for Friedel-Crafts benzylation reactions with only 1.2 equiv activated/deactivated arenes without additional solvent to access structurally and electronically diverse triarylmethanes, diarylethanes, and diarylmethanes with excellent yields and selectivities at room temperature within short reaction times.
