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

[reaction: see text] An efficient and improved procedure for the preparation of aromatic azides and their application in the Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition ("click reaction") is described. The synthesis of aromatic azides from the corresponding amines is accomplished under mild

A novel strategy for the direct conversion of aryl- and heteroarylamines to selenides has been developed via diazotization of amines with tert-butyl nitrite in neutral medium followed by reaction with diaryl/diheteroaryl/dialkyl diselenides in one pot under photocatalysis at room temperature
