The invention provides a process for the preparation of 3,3-diaryl acrylic acid amides of the formula ##STR1## in which A, B and Q are as defined in the specification, characterized by condensing a compound of formula ##STR2## with a compound of formula ZCH.sub.2 --CO--Q (III) in which Z represents a hydrogen or halogen atom, and, if an intermediate compound is formed of formula ##STR3## dehydrating the intermediate compound.
本发明提供了一种制备通式##STR1##所示的3,3-二芳基丙烯酰胺的方法,其中A、B和Q如说明书中所定义,其特征在于将通式##STR2##的化合物与通式ZCH₂--CO--Q(III)的化合物进行缩合反应,其中Z代表氢或卤素原子,并且,如果形成了通式##STR3##的中间体化合物,则对该中间体化合物进行脱水处理。
