Domino reactions between 1,1-dilithio-3,3-diphenylallene and nitriles resulted in the formation of products containing up to four nitrile molecules, representing the highest number to date of nitrile molecules involved in the formation of unambiguously characterized oligomers. The unusual domino process reported constitutes a new method for the synthesis of imidazoles. The solid-state structures of
1,1-二锂-3,3-二苯基丙二烯和腈之间的多米诺反应导致形成的产物最多含有四个腈分子,这是迄今为止参与形成明确表征的低聚物的腈分子数量最多的。报道的不寻常的多米诺骨牌过程构成了合成咪唑的新方法。通过晶体结构分析研究了空间位阻产物的固态结构。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
