palladium-catalyzed reductive carbonylation of aryl fluorosulfonates (ArOSO2F) using syngas as an inexpensive and sustainable source of carbon monoxide and hydrogen. The conversion of phenols to aryl fluorosulfonates can be conveniently achieved by employing the inexpensive commodity chemical sulfuryl fluoride (SO2F2) and base. The developed continuousflow formylation protocol requires relatively low loadings for palladium
We report a new air‐stable PdI dimer, [Pd(μ‐I)(PCy2tBu)]2, which triggers E‐selective olefin migration to enamides and styrene derivatives in the presence of multiple functional groups and with complete tolerance of air. The same dimer also triggers extremely rapidC−Ccoupling (alkylation and arylation) at roomtemperature in a modular and triply selective fashion of aromatic C−Br, C−OTf/OFs, and
我们报告了一种新的空气稳定的Pd I二聚体[Pd(μI)(PCy 2 t Bu)] 2,它在存在多个官能团且具有完全耐受性的情况下触发E-选择性烯烃向酰胺和苯乙烯衍生物的迁移空气 同一二聚体还可以在室温下以模块化和三重选择性的方式在聚(假)卤代芳烃中以芳族C-Br,C-OTf / OF和C-Cl键的形式快速触发C-C偶联(烷基化和芳基化)在具有邻位C-OTf的取代基的底物上显示出比以前的Pd I二聚体更好的活性。

nickel-catalyzed amination of aryl fluorosulfonates with aromatic and alkyl amines are described. Aniline is coupled to a diverse series of aryl fluorosulfonates catalyzed by the combination of CpPd(cinammyl) and Xantphos, and the relative reactivity of aryl fluorosulfonates to undergo Pd-catalyzed amination was compared with other common aryl electrophiles. In addition, we report the directamination of a phenol
