    摘要:
    长期以来,将烃类催化氧化为氧化衍生物一直是重要的研究领域,并且仍在寻找定义明确,可调节,有效,选择性和牢固的氧化(预)催化剂。为了进一步发展N-杂环卡宾(NHC)配体的适用性,本文报道了NHC /联吡啶负载的钌(II)混合氧化前催化剂[[N py ^ C NHC)Ru II(N py ^ N py)( CH 3 CN)2 ](PF 6)(CF 3 SO 3),1(N py ^ C NHC =二齿'2-吡啶基-NHC'中性配体,Npy ^ N py = 2,2'-联吡啶)由两个顺式松散结合的溶剂配体组成,已成功用于65-90%产率的各种芳香烃催化苄基CH氧化为相应的酮与温和的牺牲氧化剂NaIO 4。发现该配体主链在氧化条件下是坚固的。这些配体在钌中心周围的存在对于系统至关重要,如已知的RuCl 3 / NaIO 4和[Ru(对-cymene)Cl 2 ] 2 / NaIO 4事实证明,在相似

    Selective oxidation of benzylic C−H compounds to ketones is important for the production of a wide range of fine chemicals, and is often achieved using toxic or precious metal catalysts. Herein, we report the efficient oxidation of benzylic C−H groups in a broad range of substrates under mild conditions over a robust metal–organic framework material, MFM-170, incorporating redox-active [Cu2II(O2CR)4]
