The enantioselectivehydrogenation of 2-benzylquinolines and 2-functionalized and 2,3-disubstituted quinolines was developed by using the [Ir(COD)Cl]2/bisphosphine/I2 system with up to 96% ee. Moreover, mechanistic studies revealed the hydrogenation mechanism of quinoline involves a 1,4-hydride addition, isomerization, and 1,2-hydride addition, and the catalytic active species may be a Ir(III) complex
通过使用[Ir(COD)Cl] 2 /双膦/ I 2体系(ee高达96%)开发了2-苄基喹啉和2-官能化和2,3-二取代喹啉的对映选择性氢化。而且,机理研究表明,喹啉的氢化机理涉及1,4-氢化物的加成,异构化和1,2-氢化物的加成,并且催化活性物质可以是与氯化物和碘化物的Ir(III)络合物。

wide range of effect chemicals, are accessed by intramolecular amination of aromatic C–H bonds employing UV photolysis of N-chloroamines. The reactions show good functional group tolerance and allow access to a range of fused and bridged polycyclic structures. The homogeneous reaction conditions allow for the one-pot conversion of secondary amines to their arylated derivatives. Experimental and theoretical
The temperature required for flash pyrolytic elimination of water from -aminobenzyl alcohols and of carbon dioxide from dihydrobenzoxazinones to give azaxylylenes is considerably lowered by the presence of alumina and silica gel in the hot zone.
