DOI: 10.1021/jacs.3c03471
Abstract: Perfluoroalkyl compounds are persistent environmental pollutants due to their strong C(sp3)-F bonds. Hydrodefluorination has emerged as a potential alternative disposal method for perfluoroalkyl compounds. Although the transformation of trifluoromethyl arenes into the corresponding methyl arenes… read more here.
