Bowled over: A family of gem‐difluorinated sumanenes was synthesised, including the highly symmetric hexafluorosumanene (see figure). The favourable columnar structure is maintained upon fluorination. Substitution by electron‐withdrawing substituents increases the bowl depth and results in a large cathodic shift of the reduction potential.
击倒:将家庭宝石-difluorinated sumanenes合成,包括高度对称hexafluorosumanene(见图)。
氟化时保持良好的柱状结构。吸电子取代基的取代增加了碗的深度,并导致还原电位的大阴极移位。
