The combination of SmI2 and the conjugate base of triethylurea (TEU–) has been shown to favor the cyclization of unsaturated halides over direct reduction to a much greater extent than other SmI2-based reductants. Aryl, heteroaryl, and alkyl halides (X = Br, Cl, F) readily undergo heterocyclization and carbocyclization in the presence of SmI2/TEU–.
SMI的组合2和triethylurea的共轭碱(TEU - )已被证明有利于不饱和卤化物超过直接还原到更大的程度比其他SMI环化2系还原剂。在SmI 2 / TEU –的存在下,芳基,杂芳基和卤代烷(X = Br,Cl,F)容易发生杂环化和碳环化。
