also report an interesting direductive amination of 2-ethylbutanal. A direct reductive amination of aldehydes with anilines is performed with a ruthenium(II)-(arene) catalyst. The [RuCl2(p-cymene)]2/Ph2SiH2 catalytic system is very efficient for the synthesis of secondary amines and tertiary amines in good yields, and is highly chemoselective, tolerating a wide range of functional groups, such as NO2
摘要 用钌(II)-(芳烃)催化剂进行醛与苯胺的直接还原胺化。[RuCl 2(p- cymene)] 2 / Ph 2 SiH 2催化体系对于高效率地合成仲胺和叔胺非常有效,并且具有高度的化学选择性,可以耐受各种官能团,例如NO 2,CN,CO 2 Me,F,Cl,Br,OMe,Me,呋喃基和烷基。我们还报告了一个有趣的2-乙基丁醛二还原胺化反应。 用钌(II)-(芳烃)催化剂进行醛与苯胺的直接还原胺化。[RuCl 2(p- cymene)] 2 / Ph 2 SiH 2催化体系对于高效率地合成仲胺和叔胺非常有效,并且具有高度的化学选择性,可以耐受各种官能团,例如NO 2,CN,CO 2 Me,F,Cl,Br,OMe,Me,呋喃基和烷基。我们还报告了一个有趣的2-乙基丁醛二还原胺化反应。
