Description

General description

tert-Butyl nitrite (TBN) is an efficient NO source. TBN participates in photocatalyzed conversion of aryl- and heteroarylamines to selenides. It also participates in radical multifunctionalization reactions of aliphatic alkenes.

Application

tert-Butyl nitrite has been used as reagent:

• for diazotization and nitros­ation of alcohols, thiols, amines and cycloalkanes
• for the preparation of aryl azides from aryl amines

Other Notes

remainder 2-methyl-2-propanol
