New methods for the synthesis of 1,3-diaryltriazenes and azo dyes from arylamines are reported. Both methods involve the formation of aryl diazonium intermediates via the transnitrosation of arylamines with N-nitrososulfonamides. Each two-step transformation may be performed in one reaction vessel at room temperature with no precautions taken to exclude air or moisture. Several triazene and azo dye
