Fluoromethylation

WebCuriously, the fluoromethylation was accompanied by a Finkelstein fluorine‐bromide exchange when employing MeLi‐LiBr as the metalating agent. However, the simple replacement of MeLi‐LiBr complex with MeLi furnished the desired monofluoromethylketone (Scheme 3 ). Download : Download full-size image Scheme 3. WebTri(9-anthryl)borane was successfully applied as an organophotocatalyst for the visible-light-induced trifluoromethylation of unactivated alkenes with CF3I. The mild reaction conditions tolerated a variety of functional groups, and the reaction could be extended to perfluoroalkylations with C3F7I and C4F9I. Mechanistic studies revealed that the …
