Synthesis of new seven-membered benzo-fused heterocyclic ortho-dicarbonitriles
摘要:
Methods of the synthesis of new dibenz[b,f]oxepine-2,3-dicarbonitriles and dibenz[b,f]oxazepine-10,11-dicarbonitriles was developed employing as substrates 4-methyl-5-nitrophthalonitrile and 4-bromo-5-nitrophthalonitrile.
