Notes:
---The title four-membered ring compounds, naphthocyclobutenes and benzodicyclobutadienes, were produced by thermal cyclization reaction of crystalline 1,2-diallenylbenzenes and 1,6-diethynyldiallenes, respectively. These solid-state reactions proceeded efficiently and stereoselectively. The naphthocyclobutenes were shown to have extremely long C(sp3)-C(sp3) bonds (1.720-1.733 Å). The benzodicyclobutadienes were also shown to have extremely long C(sp2)-C(sp2) bonds (1.540 Å).
