X-ray diffraction. 4–9 were used as catalysts for the transfer hydrogenation of acetophenone. 4–9 showed good catalytic activity and so the effects of the different groups were also examined. For the transfer hydrogenation of acetophenone, 7–9 had similar activity to 4–6. However, the longer lifetime of 7–9 makes them more advantageous than the non-supported catalysts (4–6) in terms of catalytic cycle
通过下列反应成功地合成了3-
氨基-N-芳基-苯磺酰胺(1-3)。
间苯二胺以及各种
苯磺酰氯。然后,由[RuCl 2(p- cymene)] 2和1-3的反应制备了一系列
钌配合物(4–6)。最后,通过浸渍法制备了SiO 2负载的Ru(II)配合物(7-9)。合成的化合物和材料通过不同的方法进行了表征,例如NMR,FT-IR,TG / DTA,氮吸附-解吸(BET),
SEM和EDX。同样,通过单晶X射线衍射确定4–6的固态结构。4–9被用作催化剂的转移加氢
苯乙酮。4-9表现出良好的催化活性,因此还检查了不同组的作用。用于转移氢化
苯乙酮,7–9具有与4–6类似的活动。但是,在催化循环方面,7–9的较长使用寿命使其比非负载型催化剂(4–6)更具优势。因此,研究了SiO 2作为催化剂的效果,结果表明,过量的氧化
硅(IV)是氢化加氢的令人惊讶的活性催化剂。
苯乙酮 在这些条件下。
