The dimorphs of α-adamantyl-p-chloroacetophenone (P21/n and C2/c) undergo solid state Norrish type II cyclobutanol formation with different stereoselectivity. Based on the X-ray crystal structure data, it is concluded that conformational factors rather than packing differences control the photoproduct stereochemistry.
α-金刚烷基-对氯苯乙酮(P2 / 1 /和C2 / c)的双晶型经历了具有不同立体选择性的固态Norrish II型环丁醇形成。根据X射线晶体结构数据,可以得出结论,构象因素而不是堆积差异控制了光产物的立体化学。
