## 2- Phenyl-5-methyl-and 2,5-diphenyl-2 H-1,2,3-diazaarsoles la,b react with phenyl azide to give several crystalline products: tricyclic derivatives 2a,b and 4,4'-bis(2H-l,2,3-diazaarsoles) 5a,b formed at room temperature, and a cycloadduct 6a obtained at + 4°C. Compound 6a undergoes a fast re
Reactions of 2H-1,2,3-Diazaarsoles with Phenyl Azide. -The reaction of diazaarsoles such as (I) with phenyl azide provides tricyclic derivatives (cf. (III)), bis(diazaarsoles) (cf. (IV)), cycloadducts (cf. (V)) or theirefrom derived triazenodiazaarsoles (cf. (VI)) depending on the reaction condition
