Abstract

Abstract : CAAC–CAAC dimers with alkylene spacers are presented. These compounds are electron-rich and undergo one- and two-electron oxidation. Abstract : Herein, we report tethered cyclic(alkyl)(amino)carbene (CAAC) dimers in which two CAAC-motifs are connected by an ethylene-, trans -1, 2-cyclohexylene- and propylene-spacer through their N-centres. The 1-electron oxidized radical cations are isolable, whereas a significant influence of the bridging unit on the chemical reactivity becomes apparent in and with the 2-electron oxidized products.
