Solid-state [2+2] photodimerization of eniminium ions oriented in a head-to-tail manner controlled by cation-π interactions produced HT dimers in high yields. As the resulting dimer is readily converted to 1,3-diacetylcyclobutane, the iminium serves as a removable orientation-controlling group for the conjugated ketones.
通过阳离子-π相互作用以头对尾方式取向的烯亚胺离子的固态[2+2]光二聚反应以高产率生成HT二聚体。由于生成的二聚体很容易转化为1,3-二乙酰基环丁烷，亚胺离子可作为共轭酮的可去除取向控制基团。
