Anwendungen & Verwendung
Verwenden
tert-Butyl nitrite is employed as a reagent for diazotization and nitrosation of alcohols, thiols, amines and cycloalkanes. It plays an important role in photocatalyzed conversion of aryl and heteroarylamines to selenides. It finds application in the preparation of aryl azides from aryl amines. It is also useful for radical multifunctionalization reactions of aliphatic alkenes and source of nitric oxide.
