Ferris, J. P.; Antonucci, F. R. published the article 《Synthesis of heterocycles by photochemical cyclization of o-substituted benzene derivatives》. Keywords: ring closure benzenes photochem; indazoles irradiation anthranilonitriles; carbazole irradiation anthranilonitriles; benzimidazole irradiation anthranilonitrile; benzoxazole irradiation cyanophenol; benzofuran irradiation ethynylphenol.They researched the compound: 1,2-Benzisoxazole( cas:271-95-4 ).Name: 1,2-Benzisoxazole. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:271-95-4) here.
Irradiation of anthranilonitrile gave indazole, which on further irradiation gave benzimidazole. Irradiation of N-methyl-and N-phenylanthraniloni-trile gave 17% 1-methylindazole and 87% carbazole, resp. Irradiation of 2-cyanophenol gave 60% benzoxazole and irradiation of o-ethynylphenol gave 60% benzofuran and 20% o-AcC6H4OH.
From this literature《Synthesis of heterocycles by photochemical cyclization of o-substituted benzene derivatives》,we know some information about this compound(271-95-4)Name: 1,2-Benzisoxazole, but this is not all information, there are many literatures related to this compound(271-95-4).
