  A base induced transformation of a 1,3-dimethyl-1,3-di(1-adamantyl)formamidinium salt into β-[methyl-(1-adamantyl)amino]acrylonitriles in aliphatic nitriles

  摘要：

  A novel 1,3-dimethyl-1,3-di-(1-adamantyl)formamidinium perchlorate has been prepared via the Vilsmeier-Haack reaction of N-methyl-N-(1-adamantyl)formamide and N-methyl-N-(1-adamantyl) amine in a mixture of phosphorus oxychloride and benzene. The new formamidinium salt was found to undergo addition-elimination reactions when treated with sodium hydride in acetonitrile or propionitrile solution, thereby forming the corresponding beta-[methyl(1-adamantyl)amino]acrylonitriles and N-methyl-N-(1-adamantyl) amine. The H-1 and C-13 NMR spectra and the single-crystal X-ray structure of the new formamidinium salt have been determined along with those of the related compound 1,3-di-(1-adamantyl)-1-cyanoamidine and the corresponding beta-(dialkylamino)acrylonitriles.

  Highly efficient carbene and polycarbene catalysis of the transesterification reaction of ethyl benzoate in methanol has been observed and results in values of TON as high as 4000–6150 at a molar ratio of ester to methanol of 1:18 at room temperature. The most effective catalysts were found to be the individual carbenes or in situ generated carbenes, namely adamantyl and aromatic substituted cyclic

  已经观察到苯甲酸乙酯在甲醇中的酯交换反应的高效卡宾和聚卡宾催化，并且在室温下酯与甲醇的摩尔比为 1:18 时，TON 值高达 4000-6150。发现最有效的催化剂是单独的卡宾或原位生成的卡宾，即金刚烷基和芳族取代的环状化合物和聚合卡宾。这些反应都不需要使用分子筛。聚合咪唑-2-亚基催化剂用于从葵花油中高效生产生物柴油燃料。
