have been synthesized by Hydrotalcite catalyzed aldol condensation between 3-acetyl-2,5-dimethylfuron and substituted benzaldehydes. Yields of chalcones are more than 80%. These chalcones were characterized by their physical constants and spectral data. The group frequencies of infrared ν(cm(-1)) of CO s-cis and s-trans, CH in-plane and out of plane, CH=CH out of plane, C=C out of plane modes, NMR chemical
水滑石合成了一系列的2,5-二甲基-3-呋喃基查耳酮[2E-1-(2,5-二甲基-3-呋喃基)-3-(取代苯基)-2-丙烯-1-酮]催化3-乙酰基-2,5-二甲基呋喃与取代的苯甲醛之间的羟醛缩合。查耳酮的产率超过80%。这些查耳酮以其物理常数和光谱数据为特征。CO s-顺式和s-trans的红外ν(cm(-1))的群频率,CH面内和面外,CH = CH面外,C = C面外模式,NMR化学位移使用单回归和多回归分析,将这些查耳酮的Hα,Hβ,CO,Cα和Cβ的δ(ppm)与Hammett取代基常数,F和R参数相关。根据统计分析的结果,解释了取代基对基团频率的影响。抗菌,
