Some new bis[1-(2-aroyl-3-aryl)cyclopropylcarbonyl]benzenes and pyridines IV - VI have been prepared by the cycloaddition of dimethylsulfonium phenacylide to 1,1'-(1,3-, 1,4-phenylene, and 2,6-pyridylene)-bis(3-aryl-2-propen-1-ones) I - III by adopting two different methods. The advantages of the PTC method over the other have been discussed. The structures of the compound have been confirmed by spectral data.
一些新的双[1-(2-芳酰基-3-芳基)环丙基羰基]苯和吡啶已通过将二甲基亚砜苯乙炔与1,1'-(1,3-, 1,4-苯基和2,6-吡啶基)-双(3-芳基-2-丙烯-1-酮)进行环加成反应而制备,采用了两种不同的方法。讨论了PTC方法相对于其他方法的优势。该化合物的结构已通过光谱数据确认。
