The reactions of arylazasydnones with S- and O-nucleophiles

series of 3-arylazasydnone derivatives containing a chlorine atom and nitro group at various phenyl ring locations were functionalized by a method developed on the basis of reactions with different S- and O-nucleophiles. In all cases, an S N Ar reaction was shown to occur where the leaving group could be either a halogen or azasydnone moiety, depending on their mutual position.
