异吲哚1和2可以看作是萘稳定的烷基亚氨基桥连的辐射烯。它们在结构上的差异表现在它们的反应性上:N-甲基马来酰亚胺与1的吡咯环反应,但与2完全不反应。另一方面,四甲基脱氢苯与1和2反应得到2:1环加合物(R tBu)。
The isoindoles 1 and 2 can be regarded as radialenes of naphthalene—stabilized by bridging with alkylimino groups. Their differences in structure are manifested in their reactivity: W‐methylmaleiimide reacts with a pyrrole ring of 1, but not at all with 2. On the other hand, tetramethyldehydrobenzene reacts with 1 and 2 to give 2: 1 cycloadducts (R tBu).
