A Novel Synthesis of Arylsulfonyl Hydrazine Derivatives Via the Reaction of Arylsulfonyl Hydrazone Salts and Hydrazonoyl Chlorides
Khalili, Gholamhossein
, p. 1882 - 1886 (2014)
An efficient method for the synthesis of arylsulfonyl hydrazines and diazo compounds via arylsulfonyl hydrazone salts is described. The reaction was performed in DMF using hydrazonoyl chlorides and sodium arylsulfonyl hydrazones, which were easily prepare
Umpolung-like Cross-coupling of Tosylhydrazones with 4-Hydroxy-2-pyridones under Palladium Catalysis
Katsina, Tania,Papoulidou, Kyriaki Eleni,Zografos, Alexandros L.
, p. 8110 - 8115 (2019/10/11)
Tosylhydrazones under palladium catalysis were found to perform cross-coupling reactions with 4-hydroxy-2-pyridones. The umpolung-like reactivity, between the α-carbon of tosylhydrazone and the 3-position of the heterocycle, which is observed in the obtai
Copper-Catalyzed Formal Carbene Migratory Insertion into Internal Olefinic C=C Bonds with N-Tosylhydrazones to Access Iminofuran and 2(3H)-Furanone Derivatives
Huang, Fei,Liu, Zhuqing,Wang, Quannan,Lou, Jiang,Yu, Zhengkun
, p. 3660 - 3663 (2017/07/15)
Efficient copper-catalyzed formal carbene migratory insertion into the olefinic C=C bonds of internal olefins, that is, α-oxo ketene N,S-acetals, has been achieved by means of N-tosylhydrazones of ketones as the carbene precursors. Iminofuran derivatives
