The invention is directed to the preparation of fluorinated compounds and their use in organic synthesis. In particular, the invention is directed to methods of reacting compounds of structure with Rf-CH=N2 or (CF3)2C=N2 to form a perfluoroalkylate or -arylated compounds, and products derived from these reactions, where X, YB, and Rf are described herein.

development of diverse methods for incorporating this functional group. A recently reported route to α‐trifluoromethylatedalkylboroncompounds by an α‐transfer mechanism has now been extended to the synthesis of unprecedented, vicinally ditrifluoromethylated alkylboroncompounds in a diastereoselective fashion. The utility of these products is highlighted by conversion of the CB bond into other functional

RBF3K is a chemist's BFF: A metal‐free synthetic route to unprecedented organoboron compounds bearing an α‐trifluoromethyl substituent, employing a variety of trifluoroborate (RBF3K) starting materials, is reported. These substrates represent the first isolated α‐trifluoromethylated alkylboron building blocks, and these reagents lead to a variety of useful bench‐stable, synthetic intermediates. Pin=pinacol
