Cage compound - cage compound

Japanese: かご形化合物(籠形化合物) - かごがたかごうぶつ(英語表記)cage compound
Cage compound - cage compound
A compound in which the entire molecule is surrounded by chemical bonds such as C-C bonds like a birdcage. Natural examples include adamantane C 10 H 16 , which is extracted from petroleum (Figure). The smallest artificially synthesized cage-shaped compound is prismane C 6 H 6 , a valence isomer of benzene (a colorless, transparent liquid. It was synthesized in 1973 and was named after its prism-like shape). Prismane contains a three-membered ring, which causes a large amount of distortion, and it decomposes explosively when heated.

分子全体が鳥かごのようにC-C結合などの化学結合でかこまれている化合物。天然には,石油から産出するアダマンタンC10H16などがある(図)。人工的に合成された最小のかご形化合物としては,ベンゼンの原子価異性体であるプリズマンC6H6(無色透明の液体。1973年に合成され,プリズムのような形をしているのでこの名が付けられた。)がある。プリズマンは3員環を含んでいるためひずみが大きく,加熱すると爆発的に分解する。
