An easily available Pd(OAc)2/(2-mesitylindenyl)dicyclohexylphosphine/Me(octyl)3N+Cl−/K3PO4·3H2O catalytic system was developed and it shows high catalytic activity in the Suzuki–Miyaura cross-coupling reaction of a diverse array of aryl and heteroaryl chlorides in water. Notably, this catalytic system also works with ultra-low loading of the catalyst with high turnover numbers.
容易获得的Pd(OAc)2 /(2-异丁烯基)二环己基膦/ Me的(辛基)3 Ñ +氯- / K 3 PO 4 ·3H 2 ö催化体系被开发,它示出了在芳基和杂芳基氯化物的多样性阵列的Suzuki-Miyaura交叉偶联反应的高催化活性水。值得注意的是,该催化系统还可以在超低负荷下以高周转数运行。

Compounds having the structure of Formula I, including pharmaceutically acceptable salts of the compounds, are potent CETP inhibitors, and are useful for raising HDL-cholesterol, reducing LDL-cholesterol, and for treating or preventing atherosclerosis. In formula I, A-B is an arylamide moiety.
Dehydrogenative coupling of cyclic enones with heteroarenes has been a longstanding challenge because of the competitive ketone dehydrogenation and conjugated addition. Herein, a dehydrogenative couplingreaction of cyclic enones of different sizes with substituted thiophenes to construct β-thienyl cyclic enone compounds through palladium-catalyzed C–H functionalization under mild reaction conditions is
