Abstract

... The Journal of Organic ... Thus, this reaction proceeding as an A N -E process could not be strongly considered a successful nucleophilic 1,4-trifluoromethylation ... The fact that 1,4-adducts were not observed in these reactions suggests an important electronic effect of the R F group ...
