of an air‐stable, robust palladium/tridentate phosphane catalyst in direct CH and CCl activation reactions is reported (see scheme; DMAc=N,N‐dimethylacetamide, TBAB=tetra‐n‐butylammonium bromide). Electron‐rich, electron‐poor, and polysubstituted furans (X=O), thiophenes (X=S), pyrroles (X=NR5), and thiazoles were arylated with chloroarenes in the presence of the catalyst.
穿上它的环:在直接C中的使用对空气稳定的,坚固的钯/三齿磷烷催化剂 H和13 C 氯活化反应报道(参见方案;的DMAc = Ñ,Ñ二甲基乙酰胺,TBAB =四Ñ -丁基溴化铵)。在催化剂存在下,富电子,贫电子和多取代的呋喃(X = O),噻吩(X = S),吡咯(X = NR 5)和噻唑被氯芳烃芳基化。
