## Abstract A kinetic study is reported for S~N~A~r~ reactions of 2,4,6‐tris(trifluoromethanesulfonyl) anisole 1a with a series of para‐X‐substituted anilines 2a–e in a methanol solution at various temperatures. The substituent effects on free energy (Ξ”^β‰ ^__G__), enthalpy (Ξ”^β‰ ^__H__), and entropy (
