WebNov 1, 2024 · An efficient method for the preparation of β‐trifluoromethylporphyrins was developed through the reaction of β‐silylated Zn (II) porphyrins by using a phenanthroline and triphenylphosphine‐ligated... WebThe mild reaction conditions allow the process to tolerate many common functional groups. Perfluoroethylation with (phen)CuCF2CF3 occurs in somewhat higher yields than trifluoromethylation with (phen)CuCF3, creating a method to generate fluoroalkyl heteroarenes that are less accessible from trifluoroacetic acid derivatives.
