In another direction, the radical cyclization of thioimide with acylsilane produced simple cyclization product in low yield without expected enol silyl ether compound.

对於硫醯亚胺与矽基酮的自由基反应，则是得到低产率的简单环化产物，而不是预期的烯醇矽醚化合物。

The crystal structures of them show the photochromism is due to the photoisomerization only from enol form to keto form. According to the results of structure analyses, the intermolecular proton transfer mechanism is proposed for photochromism. We also observed their acidichromism in solution.

采用单晶XRD法得到了这五种化合物的结构，根据结构解析，推测四种光致变色化合物的变色机理可能是分子间质子转移，即吡唑啉酮由烯醇式结构变为酮式结构。
