Construction of 3-aryl-1,2,4-benzotriazines via unprecedented rearrangement of bis(benzotriazol-1-yl)methylarenes

3-Aryl-1,2,4-benzotriazines were formed unexpectedly by the treatment of 1,l-bis(benzotriazol-1-yl)methylarenes with allylsamarium bromide. A radical pathway was proposed involving steps, such as fragmentation, ring-opening, and cyclization.

1,1-Bis(benzotriazolyl) derivatives as gem-dianion synthons

Bis(benzotriazolyl)methylbenzenes 1a,b were converted by excess lithium metal in the presence of ketones into the 1,3-diols 3a-g in moderate to good yields. However, similar treatment of 5 gave only the mono reduction products 6, 7. Compounds 1a,b reacted

N-(1-Haloalkyl)pyridinium Salts: Preparation and Use for New Syntheses of Other N-(1-Substituted-alkyl)pyridinium Salts, N,N'-(1-Alkylidene)bisamines, and N,N'-(1-Alkylidene)bisbenzazoles

N-(1-Haloalkyl)pyridinium halides, obtained from an aldehyde, a thionyl halide, and pyridine, react readily with nucleophiles to yield N-(1-substituted -alkyl)pyridinium salts.N-(1-Bromoalkyl)pyridinium bromides rect readily with a wide range of nucleophiles to replace either the halogen ( by 1 mol ) or both halogen and pyridinium ( 2 mol ).They are useful precursors for the preparation of bisbenzazoles and other aminals under neutral and mild conditions.

The Chemistry of N-Substituted Benzotriazoles. Part 5. Reactions of Benzotriazole with Aldehydes and Thionyl Chloride-Formation of (Benzotriazol-1-yl)-1-chloroalkanes and Bis(benzotriazolyl)alkanes

Reaction of benzotriazole with an excess of aliphatic aldehydes and thionyl chloride in refluxing chloroform gives the corresponding 1-(benzotriazol-1-yl)-1-chloroalkanes.Products with an α-hydrogen next to the chlorine-bearing carbon atom gradually elimi
