syntheses, the new conditions allow for the first time the use of terminal alkynes. Also, it is shown that the use of alkenes, including ethylene, instead of alkynes leads to the room temperature formation of 3,4-dihydroisoquinolones. Mechanistic investigations of this new system point to a change in the turnover limiting step of the catalytic cycle relative to the previously reported conditions. Concerted

A new one-pot reaction for the regioselective construction of a six-membered fused N-heterocyclic ring leading to isoquinolones under Pd/CâCu catalysis is described.
描述了一种新的单锅反应,通过Pd/C–Cu催化,实现对六元并联N-杂环的选择性构建,生成异喹啉酮。
Direct Access to Cobaltacycles via C–H Activation: <i>N</i>-Chloroamide-Enabled Room-Temperature Synthesis of Heterocycles
Cobaltacycle synthesis via C–H activation has been achieved for the first time, providing key mechanisticinsight into cobalt catalytic chemistry. N-Chloroamides are used as a directing synthon for cobalt-catalyzed room-temperature C–H activation and construction of heterocycles. Alkynes as coupling partners allow convenient access to isoquinolones, a class of synthetically and pharmaceutically important
