N2 extrusion and co insertion: A novel palladium-catalyzed carbonylative transformation of aryltriazenes

supporting information, p. 1910 - 1913 (2015/04/27)
A novel procedure for the replacement of N2 with CO of aryltriazenes has been developed. Aryltriazenes were converted to the corresponding arylamides catalyzed by 1 mol % of PdCl2/P(o-Tol)3 under CO pressure. In this process, aryldiazonium salts were generated in the presence of 40 mol % of MeSO3H. Nitrogen was released from the substrates and CO formally inserted. Aryl bromides, iodides, alkynes, and free hydroxyl groups can be tolerated in this transformation.
Novel one-pot synthesis of thiophenols from related triazenes under mild conditions

experimental part, p. 1893 - 1896 (2012/09/22)
In this work, at first, triazenes were synthesized from primary aryl amines. Afterwards, triazenes were converted into the corresponding thiophenols in one-pot using sodium sulfide in acidic media, by in situ generation of diazonium counterion beside hydrogen sulfide as anionic sulfur nucleophile at room temperature. The procedure can be a convenient shortcut for the preparation of thiophenols from primary aryl amines. Georg Thieme Verlag Stuttgart · New York.
Nitrogen dioxide - Sodium iodide as an efficient reagent for the one- pot conversion of aryl amines to aryl iodides under nonaqueous conditions
Suzuki, Hitomi,Nonoyama, Nobuaki
, p. 4533 - 4536 (2007/10/03)
Successive treatment of aromatic amines with liquid nitrogen dioxide and powdered sodium iodide in acetonitrile at -20 °C, followed by usual work- up, gave the corresponding aryl iodides in good yield. This method worked especially well for less basic amines bearing electron-withdrawing substituents.
