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

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.

Novel tele nucleophilic aromatic substitutions in α-(benzotriazol-1-yl)alkyl aryl ketones

Reactions of α-(benzoltriazol-1-yl)alkyl aryl ketones 2 with alkyllithiums or Grignard reagents afforded para-alkylated products 5 via novel tele nucleophilic, aromatic substitutions.

A novel synthesis of esters via substitution of the benzotriazolyl group in 1-(benzotriazol-1-yl)alkyl esters with organozinc reagents

Aldehydes are converted by thionyl chloride and benzotriazole into 1-(1-chloroalyl)benzotriazoles which react with sodium carboxylates to give 1-(benzotriazol-1-yl)alkyl esters. 3. In the alternative route, 3 are prepared by substitution of one of the acetoxy groups in acylals with benzotriazole. The benzotriazolyl moiety in 3 is substituted by an alkyl, an aryl or an alkynyl group upon treatment with an organic reagent in a new versatile synthesis of esters 4.

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

REACTIVITY OF AZOLES TOWARDS BENZALDEHYDE AND ITS DIMETHYLACETAL. SYNTHESIS OF N,N'-DIAZOLYLPHENYLMETHANES

Some 1,1'-diindazolylphenylmethanes have been prepared from indazoles and benzaldehyde in presence of zinc chloride as catalyst.The reaction was strongly dependent on the basic pKa's of azoles and only few pyrazolyl derivatives could be prepare
