WebMar 1, 2024 · Photocyclization-oxidative aromatization sequence of diarylethenes, such as stilbene, is useful to construct π-expanded molecules, i.e., phenacenes, having benzene rings fused in a zigzag manner.We applied this strategy to 1,3,5-tris(arylethenyl)benzene substrates, and successfully prepared polycyclic aromatic hydrocarbons with two … WebThe studies have focused on rapid, efficient bond-fragmentation reactions initiated through photoinduced electron transfer. Electron transfer induced fragmentation of a number of donors have been examined, especially 1,2 diamines and related compounds. Two of the amines fragment with rate constants of 3 [times] 10[sup 8] to 2 [times] 10[sup 9] M[sup …
