  使用Cp * Ir（吡啶磺酰胺）Cl预催化剂对酮进行无碱转移加氢

  摘要：

  N-(2-(Pyridin-2-yl)ethyl)benzenesulfonamide derivatives and 1,1,1-trifluoro-N-(2-(pyridin-2-yl)ethyl)methanesulfonamide (1-4), along cat. with three-legged piano stool Cp*(IrCl)-Cl-III complexes (5-11) (Cp* = pentamethylcyclopentadienyl) bearing pyridinesulfonamide ligands with varying electronic parameters, were synthesized. These ligands and air-stable complexes were characterized by H-1 and C-13{H-1} NMR spectroscopy, elemental analysis, and single-crystal X-ray diffraction. Precatalysts, 5-11, were assessed for transfer hydrogenation of aryl, diaryl, dialkyl, linear, cycloaliphatic, and alpha,beta-unsaturated ketones, diones, beta-ketoesters, and a biomass-derived substrate with 2-propanol, using 1 mol % precatalyst. Catalysis was also efficient using a 0.1 mol % loading. Remarkably, all catalysis experiments can be conducted in air without dried and degassed substrates, and basic additives and halide abstractors are not required for high activity in transfer hydrogenation. Control experiments and a mercury poisoning experiment support a homogeneous catalyzed pathway. Overall, the fastest reactions are observed using electron-poor substrates and precatalysts bearing electron-rich ligands.

  A ligand-free copper(I)-catalyzed benzylic acyloxylation of 2-alkylpyridines with carboxylic acids was realized by using 1.0 atm of O2 as a green oxidant. The transformation provided a facile access to a wide range of N-heterocyclic esters through C–O bond formation, with broad substrate scope and good functional group tolerance. Preliminary mechanistic investigations showed that this protocol included

  The construction of C−N bonds by free radical reactions represents a powerful synthetic approach for direct C−H amidations of arenes or heteroarenes. Developing efficient and more environmentally friendly synthetic methods for C−H amidation reactions remains highly desirable. Herein, metal‐free electrochemical oxidative dehydrogenative C−H amidations of heteroarenes with N‐alkylsulfonamides have been

  通过自由基反应构建C-N键代表了对芳烃或杂芳烃直接C-H酰胺化的强大合成方法。为CH酰胺化反应开发高效且对环境友好的合成方法仍然是非常可取的。在此，杂芳烃与N-烷基磺酰胺的无金属电化学氧化脱氢CHH酰胺化反应已经完成。不含催化剂和化学氧化剂的CHH酰胺化反应范围广，并使用电作为绿色和唯一的氧化剂。各种杂芳烃，包括吲哚，吡咯，苯并呋喃和苯并噻吩，都经过了这种C（sp 2）-H氮化。循环伏安法研究和控制实验为无金属电催化直接生成以氮为中心的自由基提供了证据。
• Cycloauration of pyridyl sulfonamides

  The pyridyl-2-alkylsulfonamides C5H4N(CH2)nNHSO2R (n = 1,2; R = Me, Ph or p-C6H4Me) and 8-(p-tosylamino)quinoline undergo facile cycloauration reactions with H[AuCl4] in water, giving metallacyclic complexes coordinated through the pyridyl (or quinolyl) nitrogen atom and the deprotonated nitrogen of the sulfonamide group. The complexes have been fully characterised by NMR spectroscopy, ESI mass spectrometry and elemental analysis. The X-ray crystal structures of two derivatives reveal the presence of non-planar sulfonamide nitrogen atoms. The complexes show low activity against P388 murine leukaemia cells, possibly as a result of their ease of reduction with mild reducing agents.

  吡啶-2-烷基磺酰胺C5H4N(CH2)nNHSO2R（n=1,2；R=Me，Ph或对甲苯基）和8-（对甲苯磺酰胺基）喹啉在水中与H[AuCl4]发生易行的环金化反应，生成通过吡啶（或喹啉）氮原子和磺酰胺基团的脱质子氮原子配位的金属环状配合物。这些配合物通过NMR光谱、ESI质谱和元素分析得到了充分表征。两个衍生物的X射线晶体结构揭示了非平面硫酰胺氮原子的存在。这些配合物对P388小鼠白血病细胞的活性较低，可能是由于它们易于被温和的还原剂还原的结果。
