Chlorination of this amine with 'ButOCl at -16°C gave an unstable product, namely 2-dichloroarnino-3,5- difluoro-4-heptafluoroisopropyl-6-methoxy pyridine (6). Iodine-catalysed rearrangement of this dichloroamino-compound provided a ca. 70:30 mixture of 3-chloro-6-chloroimino-3,5-difluoro- 4-heptafluoroisopropyl-2-methox y -I azacyclohexa- l,4-diene (7) and 5-chloro-6-chloroirnino-3,5-difluoro-4-hepta fluoroisopropyl- 2-methoxy- 1 -azacyclohexa- l,3-diene(8). The C NMR spectra of these imines have also been studied}, keywords = {}, url = {https://jsciences.ut.ac.ir/article_31182.html}, eprint = {https://jsciences.ut.ac.ir/article_31182_b994ce12b3684c2463a4ce226820be1f.pdf} }
