Electronically Controlled Conformational Equilibria in Symmetrically Substituted 3,7,10-Triarylphenothiazines: Tuning Redox and Emission Properties
The combination of Suzuki arylation and Buchwald–Hartwig amination provides a sequentially Pd-catalyzed pseudo-four-component strategy for the synthesis of symmetrically substituted 3,7,10-triarylphenothiazines in moderate to good yields. Using p-anisyl-derived donor units and p-benzonitrile-derived acceptor units, the...
