ABSTRACT
Benzobisthiazole and thiazolothiazole derivatives are useful components in a variety of organic electronics devices resulting from their absorption, electroluminescence, and charge-transport properties. A convenient synthesis of these molecules via palladium/copper cocatalyzed C-H bond functionalization is described. Reaction conditions were optimized in a bromobenzene/benzobisthiazole system that allowed for the one-pot functionalization of both thioimidate positions of benzobisthiazole. The extension of this methodology to the synthesis of cruciform architectures and the functionalization of thiazolothiazole is also described.
