Redox-active, functionalised [3]- and [4]-dendralenes
Abstract
A series of [3]- and [4]-dendralenes, functionalised with 1,3-dithiole groups, are synthesised and shown by cyclic voltammetry to undergo reversible multi-stage redox reactions to yield tri- and tetra-cation species, respectively; the X-ray crystal structure of a [3]-dendralene derivative is reported.
