Synthetic exploitation of halogenated alkenes containing EWG: benzotriazole-mediated synthesis of benzoazetines and thermal transformations
RSC Advances Pub Date: 2014-03-27 DOI: 10.1039/C4RA01425A
Abstract
The series of stable benzoazetine derivatives (5a–d) based on nitrovinyl moieties have been synthesized via transamination of bisbenzotriazolyl derivatives (2a–c). Four new heptatomic aromatic cycloheterocumulenes (azacyclohepta-1,2,4,6-tetraene) occurring at the stage of the film-forming process by TVE have been obtained by rearrangement of benzoazetines. The highly strained products were characterized by IR spectroscopy.
