A new biaryl phosphine-containing ligand from an active palladium catalyst for ppm level Suzuki–Miyauracouplings, enabled by an aqueous micellar reaction medium. A wide array of functionalized substrates including aryl/heteroaryl bromides are amenable, as are, notably, chlorides. The catalytic system is both general and highly effective at low palladium loadings (1000–2500 ppm or 0.10–0.25 mol%).
一种新型的含钯芳基配体的活性钯催化剂,用于ppm级的Suzuki-Miyaura偶联,可通过胶束反应介质水溶液进行。包括芳基/杂芳基溴化物的各种各样的官能化底物是可取的,尤其是氯化物。在低钯载量(1000-2500 ppm或0.10-0.25 mol%)下,催化系统既通用又高效。密度泛函理论计算表明,在n表示更大的空间拥塞2 PHOS诱导周围的Pd中心增加空间拥挤,帮助动摇2:1配体的Pd(0)配合物更对于N 2 PHOS比EvanPhos(和体积更小的配体) ,从而有利于形成1:1配体– Pd o 在芳基氯化物的氧化加成反应中更具活性的络合物。

proved to be an efficient approach to 3,4-dihydro- and 1,2-dihydroquinolizinium salts and the corresponding quinolizinium derivatives by an improved thermal oxidation in the presence of Pd/C without solvent. A comparative study showed that the quinolizinium system was obtained in better yields through the 3,4-dihydroquinolizinium route, thus allowing the synthesis of quinolizinium derivatives or improvements
