    基于铑过亚im基的NHC络合物催化的二氧化碳对胺的选择性甲酰化或甲基化反应
    摘要:
    二氧化碳可以作为化学合成的可持续原料发挥至关重要的作用。为了可行,所采用的方案应尽可能温和。在本文中,我们报告了一种方法,该方法将CO 2掺入由带有基于亚吡啶的NHC /膦钳型配体的Rh(I)配合物催化的伯,仲,芳族或烷基胺中。基于perminide的配体属于通过螯合物辅助的双重CH活化获得的一类6元NHC配体。使用CO 2气球进行胺的N-甲酰化和-甲基化和苯基硅烷作为还原剂。通过改变溶剂,反应温度和所用苯基硅烷的量来调节甲酰化和甲基化产物之间的产物选择性。获得了中等到出色的转化率,以及对一系列官能团的耐受性。在催化和时程研究中与反应物的化学计量反应表明,感兴趣的甲酰化和甲基化反应始于CO 2的氢化硅烷化,然后与胺底物反应。

    The reactions of 1,8-diaminonaphthalene with paraformaldehyde and secondary phosphines (HPR2, R = Ph, Cy) directly afford N,N'-bis(phoshinomethyl)-dihydroperimidines H2C(NCH2PR2)(2)C10H6 (R = Ph (la), Cy (1b)), the methylene group of which undergoes chelate-assisted double C-H activation with [RhCl-(PPh3)(3)] to afford dihydroperimidine-derived N-heterocyclic pincer carbene (per-NHC) complexes [RhCl=C(NCH2PR2)(2)C10H6}] (R = Ph (2a), Cy (2b)). Insight into the mechanism of these C-H activation processes is provided by the reaction of 1b with [IrCl(CO)(PPh3)(2)] to provide the dihydroperimidinyl-hydrido complex [IrHCl(CO)CH(NCH2PR2)(2)C10H6}] (3b), which in turn reacts with silver salts Ag[Y] to afford, via hydride abstraction and subsequent C H activation, the per-NHC ligated salts [IrHCl(CO)=C(NCH2PR2)(2)C10H6}] ([4b]Y, Y = PF6, SbF6, PO2F2).
  • Dihydroperimidine-Derived PNP Pincer Complexes as Intermediates en Route to N-Heterocyclic Carbene Pincer Complexes
    作者:Anthony F. Hill、Caitlin M. A. McQueen

    日期:2014.4.28
    The reaction of N,N'-bis(dicyclohexylphosphinomethyl)-dihydroperimidine (H2C(NCH2PCy2)(2)C10H6-1,8, 1a) with [RuCl2(PPh3)(3)] in THF affords the perimidinylidene-based N-heterocyclic carbene (per-NHC) pincer complex [RuCl2(OC4H8)=C(NCH2PCy2)(2)C10H6}] (2) via chelate-assisted double C H activation. In contrast, the reactions of the tetraphenyl analogue H2C(NCH2PPh2)(2)C10H6 (1b) with [RuCl2(PPh3)(3)] and of la with [RuCl(R)(CO)(PPh3)(2)] (R = Ph, CH=CHPh) do not result in C-H activation but rather give the asymmetric, PNP-coordinated complexes [RuCl2(PPh3)kappa P-3,N,P'-CH2(NCH2PPh2)(2)C10H6}] (3) and [RuCl(R)(CO)-kappa(3) P,N,P'-CH2(NCH2PCY2)(2)C10H6}] (R = Ph (4), CH=CHPh (5)), respectively, in which the ruthenium migrates rapidly between nitrogen donors. This provides insight into the mechanistic pathway by which the proligands 1 undergo per-NHC formation, as demonstrated by the thermal conversion of 4 to [RuHCl(CO)=C(NCH2PCy2)(2)C10H6}] (6) and benzene.
