thienylmagnesium species generated in situ is more stable than the corresponding thienyllithium species, which was applied to trap the transient anion species with several electrophiles, such as allyl iodide, phenyl isocyanate, and tributylstannyl chloride. The utility of the magnesium bisamide-mediated halogen dance is useful in the concise synthesis of a medicinally advantageous compound via a one-pot, ester-directed
描述了双酰胺镁介导的溴噻吩的卤素舞。原位生成的噻吩基镁物种比相应的噻吩基锂物种更稳定,噻吩基锂物种被用于用几种亲电试剂(例如烯丙基碘,苯基异氰酸酯和三丁基锡烷基氯)捕获瞬态阴离子物种。双酰胺镁介导的卤素舞的效用可用于通过一锅,酯导向的卤素舞/ Negishi交叉偶联的医学上有利的化合物的简明合成。
