The intramolecular elimination of isobutene from 2-d,-triisobutylaluminum has been studied in the gas phase for temperatures ranging between 102.4 and 184.6'C. The reaction is apparently homogeneous and obeys the first order rate law, yielding the following Arrhenius relationship: log kelim (sec-')

## 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 (Δ^≠^__G__), enthalpy (Δ^≠^__H__), and entropy (
