An azepine ring as an exotic fusing motif in the 21‐carbaselenaporphyrinoid dyads is reported by Anna Berlicka, Lechosław Latos‐Grażyński et al. in their Communication (e202314925). The covalently linked dyads exhibit a unique geometry, characterized by a canted arrangement of two carbaselenaporphyrinic planes. The dimerization process occurs via a [5+2] cycloaddition reaction.
The oxidation of 10,15‐diaryl‐21‐carba‐23‐selenaporphyrinoids resulted in the creation of dyads. The dimerization process follows a [5+2] cycloaddition path with the formation of an azepine unit. The arrays display two direct bonds between the peripheral carbocyclic carbon atoms of one carbaselenaporphyrinic subunit and the central carbon and nitrogen atoms of the second subunit. This results in a...
