(sp3)−H bond. It was found that complex 1 exhibited excellent catalytic activity for hydrosilylation of aldehydes and ketones. The catalytic system showed good tolerance and catalytic activity for the substrates with different functional groups on the benzene ring. It is worth mentioning that, the experimental results showed that both ketones and aldehydes could be reduced in good to excellent yields under
通过C (sp 3 )-H 键活化与零价
铁配合物Fe (PMe 3 ) 4合成了一种新型亚甲
硅烷负载的氢化
铁[Si, C]FeH (PMe 3 ) 3 ( 1 ) 。通过光谱方法和单晶 X 射线衍射分析对配合物1进行了充分表征。据我们所知,1是第一个通过活化 C (sp 3 )-H 键产生的基于甲
硅烷基的氢化螯合
铁络合物的例子。发现复杂1对醛和酮的氢化
硅烷化表现出优异的催化活性。该催化体系对苯环上不同官能团的底物表现出良好的耐受性和催化活性。值得一提的是,实验结果表明,在相同的催化条件下,
酮类和
醛类均能以良好的收率被还原。根据实验和文献报道,提出了一种可能的催化机制。
