available precursors remains a synthetic challenge. The metal‐free hydrofluorination of alkynes constitutes an attractive though elusive strategy for their preparation. Introduced here is an inexpensive and easily handled reagent that enables the development of simple and scalable protocols for the regioselective hydrofluorination of alkynes to access both the E and Z isomers of vinyl fluorides. These

Palladium-catalyzed decarboxylative coupling reactions using alkynoic acids and 1-fluoro-2,2-diiodovinylarenes provide mono- and dialkynylfluoroalkenes with high selectivity. When the reaction was conducted using DBU/DMSO, the hydrodeiodinated monoalkynylfluoroalkene product was formed, whereas performing the reaction using Et3N/THF gave the dialkynylfluoroalkene product. Both reaction conditions gave high yields of
使用炔酸和1-氟-2,2-二碘乙烯基芳烃的钯催化的脱羧偶联反应可提供高选择性的单-和二-炔基氟烯烃。当使用DBU / DMSO进行反应时,形成了加氢碘化的单炔基氟代烯烃产物,而使用Et 3 N / THF进行反应则得到了二炔基氟代烯烃产物。两种反应条件均产生了高产率的带有氟原子的所需烯炔和乙炔产物。
Metalloradical activation of carbonyl azides for enantioselective radical aziridination
The carbonyl azide TrocN3 (2,2,2-trichloroethoxycarbonyl azide) is a potent nitrogen radical precursor for radical olefinaziridination via Co(II)-based metalloradical catalysis (MRC). The cobalt(II) complex of D2-symmetric chiral amidoporphyrin 3,5-DitBu-QingPhyrin proves to be an efficient catalyst that can activate TrocN3 at room temperature to aziridinate various styrene derivatives, providing
Inter- and intramolecular cycloaddition reactions of ethenetricarboxylates with styrenes and α-halostyrenes have been investigated. The reactions of ethenetricarboxylates with styrenes or α-bromostyrenes in the presence of SnCl4 or SnBr4 stereoselectively gave 2,4-cis-substituted cyclobutanes. The intramolecular cycloaddition reactions of a series of styrene-functionalized ethenetricarboxylate amides
