Resumen: Several systems formed by two allyl fragments linked by four arenediyl tethers have been studied through DFT calculations. A delocalised bis(allyl) system, similar to Cope rearrangement transition states, is preferred for derivatives bearing 5-membered ring tethers, as a result of the large strain in the related localised geometry Idioma: Inglés DOI: 10.1039/c4ra16381h Año: 2015 Publicado en: RSC Advances 5, 15 (2015), 11494-11497 ISSN: 2046-2069 Factor impacto JCR: 3.289 (2015) Categ.
