Abstract
DIPEA was found to be an excellent sulfur activator to promote the reaction of 2-nitrochalcones with elemental sulfur. A wide range of 2-benzoylbenzothiophenes was obtained as a result of a cascade of alkene C═C bond thiolation, aromatic sulfur-denitration.
摘要
二异丙基乙胺被发现是一种出色的硫活化剂，可促进 2-硝基查耳酮与单质硫的反应。通过烯烃 C═C 键硫代、芳基硫脱氮的级联反应，得到了广泛的 2-苯甲酰苯并噻吩。
