Rapid [1,5] Hydrogen Migration on 7-Alkoxycarbonyltropilidenes under Conformational Regulation
摘要:
The thermal [1,5] hydrogen migration of 7-alkoxycarbonyltropilidene was found to be accelerated by conformational regulation at the carbonyl group, which was mainly affected to the activation energy. Methyl substitutions on the 3- and 5-positions further increased the migration rate.
