Palladium-Catalyzed Insertion of N-tosylhydrazones and Trapping with Carbon Nucleophiles 来自 国家科技图书文献中心 喜欢 0 阅读量: 31 作者:P Zhou,Y Ye,Y Liang 摘要: A novel and mild Pd-catalyzed three-component coupling of vinyl iodides, tosylhydrazones, and carbon nucleophiles is developed.关键词...
(B) This work: ligand-enabled silver-catalyzed site-selective C–H benzylation of alkanes with N-triftosylhydrazones as the donor carbene precursor, leading to alkyl aromatics. EWG, electron-withdrawing group; EDG, electron-donating group; r.r., regioisomeric ratio of 3°, 2° and 1° C–...
摘要: In this chapter, alkene synthesis based on the reaction of N-tosylhydrazones is described. The reactivity of tosylhydrazones is determined by either the acidity of α-proton and hydrazone...关键词: organic chemistry, review alkenes (acyclic compounds catalysis, phase‐transfer catalysis C‐C ...
C(sp)–C(sp 3 ) Bond Formation through Cu-Catalyzed Cross-Coupling of N -Tosylhydrazones and Trialkylsilylethynes Copper-catalyzed cross-coupling of N -tosylhydrazones with trialkylsilylethynes leads to the formation of C(sp)–C(sp 3 ) bonds. Cu carbene migratory inser......
