使用

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.

一般的な説明

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.

純化方法

If it is free from OH bands (IR) then distil it through a 12inch helices packed column under reduced pressure, otherwise wash with aqueous 5% NaHCO3 (effervescence), then H2O, dry (Na2SO4) and fractionate it through a 10 theoretical plates column at ca 10mm pressure.
