A reaction between ethyl α-cyanocinnamate and o-phenylenediamine under thermal conditions yielded 2-cyano-3-phenyl-propionic acid ethyl ester, 2-phenyl benzimidazole, and ethyl cyanoacetate. The mechanistic revelations led to the development of a simple and efficient transfer-hydrogenation process from the in situ generated benzimidazolines to activated olefins under solventless and catalyst-free conditions.
在热条件下,乙基α-氰基肉桂酸酯与邻苯二胺的反应生成了2-氰基-3-苯基丙酸乙酯、2-苯基苯并咪唑和乙基氰乙酸酯。机制上的揭示促成了一种简单高效的转移氢化过程,从原位生成的苯并咪唑啉到活化烯烃,在无溶剂和无催化剂的条件下进行。
