The intermolecular and intramolecular reductive coupling reactions of arylmethylidenemalononitriles induced by SmI2 have been studied. The configuration of the cyclodimerization products, 4,5-trans-isomers of 2-amino-1,3,3-tricyano-4,5-diarylcyclopentenes, has been confirmed by X-ray analysis and a possible reaction mechanism is proposed.
已经研究了由SmI2诱导的芳基甲叉马龙腈的分子间和分子内还原偶联反应。通过X射线分析确认了环二聚化产物的构型,即2-氨基-1,3,3-三氰基-4,5-二芳基环戊烯的4,5-反式异构体,并提出了一种可能的反应机制。
