Abstract
AbstractThe cover picture shows a cyclohexallene‐based starry night over the cathedral of Santiago de Compostela in northwest Spain. 1,2‐Cyclohexadiene is a highly reactive cyclic allene that is usually generated by the use of strong bases or highly nucleophilic reagents, and this limits its scope. Herein we described an improved method to generate this molecule by fluoride‐induced β‐elimination of the corresponding 6‐(trimethylsilyl)cyclohexenyl triflate. This method allows the generation of this strained cyclic allene under mild reaction conditions and with higher efficiency than classical approaches, as demonstrated by trapping experiments based on cycloaddition reactions. Details are discussed in the article by D. Peña et al. on p. 5519 ff.
