A wide variety of alkoxymethyltrifluoroborate substrates were prepared via SN2 displacement of potassium bromomethyltrifluoroborate with various alkoxides in excellent yields. These alkoxymethyltrifluoroborates were effectively cross-coupled with several arylchlorides. This method provides a unique dissonant disconnect that allows greater flexibility in the design of new and improved synthetic pathways
