In a recent publication2 the mechanism of the reaction of i-arylethyltrimethylammonium ions with ethoxide ion in ethanol at 70ยฐ was shown to be E2. The transition state for this process involved extensive proton transfer to base as exhibited by the observed trend in hydrogendeuterium isotope effects
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-')
