Interplay of dual reactivity in the reaction of pentafulvenes with 1,2,4-triazoline-3,5-diones: experimental and theoretical investigations†‡
Abstract
A detailed investigation on the reaction of pentafulvenes with N-substituted-1,2,4-triazoline-3,5-diones leading to the formation of five- and seven-membered azapolycycles is described. The observed reactivity is explained based on the electronic and frontier
