Description
- General description: Hydroxylamine-O-sulfonic acid (HOSA), an O-substituted hydroxylamine, is a widely used aminating agent.[1] It can behave as a nucleophile as well as an electrophile.[2] The conversion of organoboranes obtained from hydroboration of olefins to amines using HOSA has been reported.[3]
- Application: Hydroxylamine-O-sulfonic acid (HOSA) may be used to synthesize (Z)-1H-purin-6(7H)-ylideneaminooxysulfonic acid.[4] HOSA may be used as an aminating reagent in the synthesis of:1-aminotetrazoles and 2-aminotetrazoles[5]N-aminopiperidine (NAPP)[6]1H,1′ H-2,2′-biimidazole-1,1′-diamine[7]
