| 摘 要： | 利用2,3-二(二苯膦氧基)-1,3-丁二烯与胺的迈克尔加成反应,合成了单胺基及环胺基改性的有机氧化膦,经有机硅烷还原,制备出胺基取代的膦配体,所得化合物经NMR及单晶X射线衍射分析.考察了所得配体与Ru(PPh3)3Cl2组成的催化体系在苯乙酮氧转移反应中的催化活性,发现氧化膦与Ru原位形成的催化剂比其还原态的三价膦组成的催化剂催化活性还高,二胺基取代的二氧化膦配体具有较高的催化活性,TON可达273.而采用先制备催化剂再催化反应时配体6的钌络合物催化活性TON可达352.

| Abstract: | A series of mono and cyclic amines modified by phosphine oxides have been synthesized by Michael addition reaction of 2,3-bis(diphenylphosphinyl)-1,3-butadiene with amine.Then the phosphine oxide was reduced by silane to give amine modified by phosphine.The obtained compounds were characterized by NMR and X-ray diffraction.The activity of catalyst system formed in situ of modified phosphine ligands with Ru(PPh3)3Cl2 in catalytic hydrogen transfer reaction of acetophenone was evaluated.It is found that the a... |
