创新高校基础有机化学教学的探索——用红黑笔判断电环化产物构型的方法

介绍一种通过红黑笔来判断电环化产物立体构型的方法,该方法具有红色、黑色区分明显,轨道翻转和旋转灵活,立体感强,道具简单易得等特点,且能解放双手,特别适合课堂教学,取得了很好的教学效果。最后,还列举了一些该方法应用的实例。

This paper introduced a method to determine the configuration of electrocyclic products via red-black gel pens. This method exhibited several features, including obviously distinguishingthe red and black, flexibly flip and rotatingthe orbital, strong tridimensional sense, and easily available materials. Especially, it could release our hands, which was suitable for classroom teaching.This method has acquired good teaching effect. Finally, several examples were listed employing the red-black gel pens method.
