Dipolar addition reactions of nitrileoxides. III the reaction of benzonitrileoxides with sulphonic and carboxylic acid chlorides

One-pot synthesis of trisubstituted ureas from α-chloroaldoxime O-methanesulfonates and secondary amines

“…14 Rajagopalan and Talaty also showed that pyrrolidine could undergo substitution reaction with a-chloroaldoxime Omethanesulfonate to give amidoxime intermediate. 15 Based on these studies, including Yamamoto's nding 10a and our results, we proposed two highly possible pathways. measured on Perkin Elmer Spectrum GX FT-IR system and recorded on wave number (cm À1 ).…”

Synthesis of α-Chloroaldoxime O-Methanesulfonates and Their Use in the Synthesis of Functionalized Benzimidazoles

“…Despite the significant synthetic potential of these compounds, less attention has been received. Few examples exist for the synthesis of these compounds, and only one synthetic application had appeared in the literature, that is to synthesize 1,4,2-dithiazolium salt . This is plausibly due to the lack of general information of the chemical properties (stability, reactivity, etc.)…”
