Abstract

B←N coordination supports a [2+2] photodimerization in the solid state. The bond is defined by an orthogonal interaction between stilbazole and a phenylboronic ester to enable a stereocontrolled and rapid photoreaction. The cyclobutane photoproduct affords a novel diboron bis-tweezer adduct that is used to separate a mixture of benzene and thiophene upon crystallization.

摘要

硼与氮的配位作用在固态下支持[2 + 2]光环化二聚反应。该键由芪唑与苯基硼酸酯之间的正交相互作用定义，以实现立体控制的快速光反应。环丁烷光产物提供了一种新型的双硼双钳形加合物，该加合物在结晶时用于分离苯和噻吩的混合物。
