Palladium-Catalyzed Carbonylative Reactions of 1-Bromo-2-fluorobenzenes with Various Nucleophiles: Effective Combination of Carbonylation and Nucleophilic Substitution

systematic study on the carbonylative transformation of 1-bromo-2-fluorobenzenes with various nucleophiles has been performed. Different types of double nucleophiles, such as N-N, N-C, O-C, and N-S, can be effectively applied as coupling partners. The cor

1,2,3-Benzotriazin-4-ones and Related Systems. Part 6. Thermal and Photolytic Decomposition of 3-Arylideneamino-, 3-Imidoyl-, and 3-Heteroaryl-1,2,3-benzotriazin-4-ones

Thermal decomposition of 3-arylideneamino- and 3-imidoyl-1,2,3-benzotriazin-4-ones in solution gives 2-arylquinazolin-4-ones and 1,2-diaryl-1,4-dihydroquinazolin-4-ones, respectively.In the latter decompositions phenanthridones are also formed in minor but substantial (20percent) yield.Possible mechanisms to account for these products are discussed.Photolysis of the 3-arylideneamino-derivatives in methanol provides a useful synthesis of aldehyde o-(methoxycarbonyl)phenylhydrazones. 3-(α-Pyridyl)- and 3-thiazol-2-yl-1,2,3-benzotriazin-4-one undergo thermal decomposition to pyridoquinazolin-11-one and thiazoloquinazolin-5-one, respectively.
