  Skeletal Rearrangement of Cyano-Substituted Iminoisobenzofurans into Alkyl 2-Cyanobenzoates Catalyzed by B(C₆F₅)₃

  摘要：

  An efficient method for the direct conversion of cyano-substituted iminoisobenzofurans into their corresponding alkyl 2-cyanobenzoates has been developed. This transformation proceeds via cleavage of C-C, C-O, and C-N bonds in starting iminoisobenzofurans. DFT study revealed that intermediate a-iminonitriles are produced in situ via C-C bond formation between 2-iminium benzoates and a cyanide ion. Generation of isocyanide as the byproduct in a more thermodynamic manner in DFT calculations also supports the experimental results.

• Efficient Carbonylation of Aryl and Heteroaryl Bromides using a Palladium/Diadamantylbutylphosphine Catalyst

  日期：2006.7

  A general palladium-catalyzed alkoxycarbonylation of aryl and heteroaryl bromides has been developed in the presence of bulky monodentate phosphines. Studies of the butoxycarbonylation of three model substrates revealed the advantages of di-1-adamantyl-n-butylphosphine compared to other ligands. In the presence of this catalyst system various bromoarenes provided the corresponding benzoic acid derivatives

  在庞大的单齿膦存在下，已开发出一般的钯催化的芳基和杂芳基溴化物的烷氧基羰基化反应。三种模型底物的丁氧基羰基化研究表明，与其他配体相比，二-1-金刚烷基-正丁基膦具有优势。在该催化剂体系的存在下，各种溴代芳烃以低产率（0.5mol％Pd或更低）以优异的产率提供了相应的苯甲酸衍生物（酯，酰胺，酸）。
