Homolytic ring fission in small, strange bicyclic molecules
, 1984 The homolytic ring fission of strained bicycloalkyl radicals was investigated by E.S.R. spectroscopy. These bicycloalkyl radicals provided examples of cycloalkyl-, cyclopropylmethyl-, and cyclobutylmethyl-type radicals in which the preferred mode, and rate of β-scission could be studied. Three types of compounds were investigated; i.e.

Chemistry Teacher Trainees’ use of Molecular Models in Learning Spiro and Bicyclic Compounds
Science Education International, 2022 The study diagnosed chemistry teacher trainees’ difficulties in naming and writing structures of spiro and bicyclic compounds. The case study design was conducted in a constructivist environment to enhance chemistry teacher trainees’ ability to construct,

Indole as a regulator of bacterial physiology
Mexican Journal of Medical Research ICSA, 2023 During the last years, indole has been the subject of study, this is chemically defined as an aromatic bicyclic heterocycle, from the synthesis of tryptophan after its degradation by tryptophanase (TnaA); in turn has been implicated as a signalling ...

, 2017 We call iodabenzene a cyclic (CH)5I molecule. A planar iodabenzene would have 8 π electrons, a situation best avoided by an out-of-plane distortion to a bird-like geometry.
