Eyring Analysis: An Eyring analysis was conducted using 4-bromoanisole as a substrate across 363 -378 K temperature range at 5 K intervals. Under these condiQons (kineQc regime 1), there is expected to be no or very liele net influence of substrate electronics on the rate of reacQon. The acQvaQon energy and acQvaQon entropy were derived as DH ‡ = +16.0 kcal mol -1 and DS ‡ = -36.6 cal K -1 mol -1 .
