Abstract
2,6-Di(hetero)aryl and 2-(hetero)aryl substituted dithienothiazines are prepared from N-aryl dithienothiazines by a lithiation-lithium-zinc exchange-Negishi cross-coupling sequence with (hetero)aryl iodides in a one-pot fashion in good to excellent yields. These novel extended π-electron systems can be reversibly oxidized and fine-tuned in their electronic properties as supported by cyclo voltammetric, and absorption and emission spectroscopic studies.
