Abstract
Use of the phenyldiazenyl group, which serves as a protecting group for secondary amines is described in detail. The triazene protected amine is compatible with oxidative and reductive conditions as well as with strong bases (LDA, tert-butyllithium) and alkylating reagents. The amine is regenerated by action of trifluoroacetic acid and a suitable reducing agent (EtOH or NaH2PO2).
