Redox-controlled chalcogen and pnictogen bonding: the case of a sulfonium/stibonium dication as a preanionophore for chloride anion transport.

ABSTRACT: Our interest in the chemistry of tunable chalcogen and pnictogen bond donors as Lewis acidic platforms for the complexation and transport of anions has led us to investigate examples of such compounds that can be activated by redox events. Here, we describe the synthesis of [o-MePhS(C₆H₄)SbPh₃]²⁺ ([3]²⁺) and [o-MePhS(C₆H₄)Sb(p-Tol)₃]²⁺ ([4]²⁺), two dicationic stibonium/sulfonium bifunctional Lewis acids which were obtained by methylation of the phenylthioether derivatives [o-PhS(C₆H₄)SbPh₃]⁺ ([1]⁺) and [o-PhS(C₆H₄)Sb(p-Tol)₃]^+</
