由两个不同的环二烯组成的二元共晶的光照射产生高度对称的立方烷样四酸笼区域选择性和定量产率。该笼通过二烯共晶组分之一的双[2+2]光二聚形成。第二个二烯，而光稳定的共晶反应中的双[2+2]光二聚作为一个纯的形式定量地形成一个四甲基立方烷类笼。笼的立体化学在结构上得到验证。
Photoirradiation of a binary cocrystal composed of two different cyclic dienes generates a highly-symmetric cubane-like tetraacid cage regioselectively and in quantitative yield. The cage forms by a double [2+2] photodimerization of one of the diene cocrystal components. The second diene while photostable in the cocrystal reacts in a double [2+2] photodimerization as a pure form quantitatively to form a tetramethyl cubane-like cage. The stereochemistry of the cage is structurally authenticated.
