摘要

The commercially available and experimentally convenient (bp 65 degrees C) difluoromethyltrimethylsilane (TMSCHF2) is proposed as a valuable difluoromethylating transfer reagent for delivering the CHF2 moiety to various heteroatom-based electrophiles. Upon activation with an alkoxide, a conceptually intuitive nucleophilic displacement directly furnishes in high yields the bench-stable analogues.
