  A general, efficient iron‐catalyzed α‐alkylation of nitriles with primary alcohols through a hydrogen‐borrowing pathway has been developed, allowing a wide variety of alkylated nitriles to be readily accessible. Detailed mechanistic studies suggest that the reaction proceeds via an olefin intermediate with the turnover rate limited by the hydrogenation of the olefin with an iron hydride. Apart from

  已经开发了一种普遍的，通过氢借入途径与伯醇进行的高效铁催化的腈与伯醇的α-烷基化反应，使各种烷基化的腈均易于获得。详细的机理研究表明，反应是通过烯烃中间体进行的，其转化率受烯烃与氢化铁的氢化作用所限制。除了参与烷基化以外，还发现腈在促进活性催化物质的形成和稳定中起着重要作用。

  The chemoselective alkylation and olefination of alkylnitriles with alcohols have been developed by simply controlling the reaction atmosphere. A binuclear rhodium complex catalyzes the alkylation reaction under argon through a hydrogen‐borrowing pathway and the olefination reaction under oxygen through aerobic dehydrogenation. Broad substrate scope is demonstrated, permitting the synthesis of some

  通过简单地控制反应气氛，已经开发了烷基腈与醇的化学选择性烷基化和烯化。双核铑配合物可通过氢借入途径催化氩气下的烷基化反应，而需氧脱氢则可催化氧气下的烯化反应。展示了广泛的底物范围，可以合成一些重要的有机结构单元。机理研究表明，烷基化产物可通过氢化铑将烯烃中间体共轭还原而形成，而烯烃产物的形成可能是由于氢化铑络合物与分子氧的氧化所致。

  backbone-modified N-heterocyclic carbene (NHC) complexes of iridium(I) (1d–f) have been synthesized and characterized. The electronic properties of the NHC ligands have been assessed by comparison of the IR carbonyl stretching frequencies of the in situ prepared [IrCl(CO)2(NHC)] complexes in CH2Cl2. These new complexes (1d–f), together with previously prepared 1a–c, were applied as catalysts for the α-alkylation

  合成并表征了一系列骨架修饰的铱（I）（1d–f）的N-杂环卡宾（NHC）配合物。通过比较在CH 2 Cl 2中原位制备的[IrCl（CO）2（NHC）]配合物的IR羰基拉伸频率，可以评估NHC配体的电子性质。这些新的配合物（1d–f）以及先前制备的1a–c将其用作等摩尔量的伯醇或2-氨基苄醇的芳基乙腈的α-烷基化催化剂。这些配合物的催化活性可以通过修饰NHC配体的N-取代基和主链来控制。NHC-Ir I络合物1f在N原子上带有4-甲氧基苄基取代基，在咪唑的4,5-位带有4-甲氧基苯基，在芳基乙腈与伯醇的α-烷基化反应中表现出最高的催化活性。在空气气氛中，在非常短的反应时间内，通过使用0.1 mol％1f和催化量的KOH（5 mol％），通过借用氢途径以高收率获得了各种α-烷基化的腈和氨基喹啉。

  A practical method to synthesize α‐alkylated arylacetonitriles from arylacetonitriles and alcohols without using any expensive transition metal complexes is demonstrated here. Following this base‐catalysed sustainable procedure, various arylacetonitriles were successfully alkylated with different alcohols. The practical applicability of this protocol was extended by one‐pot synthesis of important carboxylic

  Aminocyclopentadienyl ruthenium complexes, [(η5-C5H4NMe2)Ru(PPh3)2(CH3CN)]+BF4− and [(η5-C5H4NEt2)Ru(PPh3)2(CH3CN)]+BF4−, are moderately active catalysts for α-alkylation of arylacetonitriles with primary alcohols; on the other hand, the analogous unsubstituted cyclopentadienyl ruthenium complex [(η5-C5H5)Ru(PPh3)2(CH3CN)]+BF4− shows very low catalytic activity. On the basis of experimental results and theoretical calculations, rationalization for the much higher catalytic activity of the aminocyclopentadienyl complexes over that of the unsubstituted Cp complex is provided. In the catalytic systems with the former, it is possible to regenerate the active solvento complexes via protonation of the metal hydride intermediates and subsequent ligand substitution; this process is, however, very nonfacile in the catalytic system with the latter.

  氨基环戊二烯基钌配合物 [(η⁵-C₅H₄NMe₂)Ru(PPh₃)₂(CH₃CN)]⁺BF₄⁻ 和 [(η⁵-C₅H₄NEt₂)Ru(PPh₃)₂(CH₃CN)]⁺BF₄⁻ 是对芳基乙腈与初级醇的α-烷基化反应具有适度活性的催化剂；另一方面，类似的未取代环戊二烯基钌配合物 [(η⁵-C₅H₅)Ru(PPh₃)₂(CH₃CN)]⁺BF₄⁻ 显示出非常低的催化活性。根据实验结果和理论计算，对氨基环戊二烯基配合物相较于未取代Cp配合物的催化活性显著更高的原因进行了合理解释。在采用前者的催化体系中，可以通过金属氢化物中间体的质子化和随后的配体置换来再生活性溶剂配合物；然而，在后者的催化体系中，这一过程则非常不易。
