二苯基环丁烯二酮（Ia）及其亚胺衍生物（Ib）在异腈存在下的光解，通过共轭双烯酮（IIa）和烯酮-烯酮亚胺（IIb）中间体，得到扩环产物（IIIa）和（IIIb）。低温光解过程中的光谱。
The photolysis of diphenylcyclobutenedion (Ia) and its imine derivative (Ib) in the presence of an isonitrile gives ring-expanded products (IIIa) and (IIIb)via conjugated bis-ketene (IIa) and ketene-ketenimine (IIb) intermediates, which were confirmed by the photolysis of (I) in methanol to give succinate (IV) and directyl by i.r. spectroscopy during low temperature photolysis.
