Beschreibung

Allgemeine Beschreibung

Hydroxylamine-O-sulfonic acid (HOSA), an O-substituted hydroxylamine, is a widely used aminating agent. It can behave as a nucleophile as well as an electrophile. The conversion of organoboranes obtained from hydroboration of olefins to amines using HOSA has been reported.

Anwendung

Hydroxylamine-O-sulfonic acid (HOSA) may be used to synthesize (Z)-1H-purin-6(7H)-ylideneaminooxysulfonic acid.
HOSA may be used as an aminating reagent in the synthesis of:

• 1-aminotetrazoles and 2-aminotetrazoles
• N-aminopiperidine (NAPP)
• 1H,1′ H-2,2′-biimidazole-1,1′-diamine
