Nazarov Cyclization and Oxo-Diels–Alder Reaction of Chalcones Induced by the Naked Silver Cation in Gas Phase

Abstract

This paper reports here Nazarov cyclization and oxo-Diels–Alder reaction induced by the naked silver cation in the collisional activation of silver(I)/chalcone complexes, which lead to the final elimination of AgOH and AgH, respectively. Deuterium labeling experiments, DFT calculations, and the substituent effect were utilized to confirm the reaction mechanisms.
