A series of α-thio- and seleno-alkyl-lithiums add to chalcone mainly at the C-3 site in tetrahydrofuran (THF) and quite exclusively at its C-1 site in THF–hexamethylphosphoric triamide; these results contrast with those previously described for other enals and enones.
查尔酮中一系列α-硫代和硒代烷基锂主要在四氢呋喃(THF)的C-3位加成,而在THF-六甲基磷酸三酰胺的C-1位加成。这些结果与先前针对其他烯类和烯酮的描述相反。
