  Rhodium-Catalyzed Silylation and Intramolecular Arylation of Nitriles via the Silicon-Assisted Cleavage of Carbon−Cyano Bonds

  摘要：

  A rhodium-catalyzed silylation reaction of carbon-cyano bonds using disilane has been developed. Under these catalytic conditions, carbon-cyano bonds in aryl, alkenyl, allyl, and benzyl cyanides bearing a variety of functional groups can be silylated. The observation of an enamine side product in the silylation of benzyl cyanides and related stoichiometric studies indicate that the carbon-cyano bond cleavage proceeds through the deinsertion of silyl isocyanide from eta(2)-iminoacyl complex B. Knowledge gained from these studies has led to the development of a new intramolecular biaryl coupling reaction in which aryl cyanides and aryl chlorides are cross-coupled.

  A flow microreactor system consisting of micromixers and microtube reactors provides an effective tool for the generation and reactions of aryllithiums bearing an alkoxycarbonyl group at para‐, meta‐, and ortho‐positions. Alkyl p‐ and m‐lithiobenzoates were generated by the I/Li exchange reaction with PhLi. The Br/Li exchange reactions with sBuLi were unsuccessful. Subsequent reactions of the resulting

  earlier investigation, we presented evidence based on Hammett σ-constants that the trimethylsilyl [(CH_3)_3Si-] group is electron-donating in character as judged by the manner in which it influences the acidity of the carboxyl group in benzoic acid. Since the electrical influence of the group is not apparently clear-cut in other types of compounds we have reinvestigated the reactivities of the trimethylsilyl

  在较早的调查中，我们提供了基于 Hammett σ 常数的证据，表明三甲基甲硅烷基 [(CH_3)_3Si-] 基团具有供电子特性，根据它影响苯甲酸中羧基酸度的方式来判断。由于该基团的电影响在其他类型的化合物中并不明显，我们重新研究了三甲基甲硅烷基取代的苯甲酸的反应性，并制备了相应的乙酯并确定了它们的碱性皂化率。
