A rapid access to 2,2′‐bithiazole‐based copolymers has been developed on the basis of the sequential palladium‐catalyzed CH/CX and CH/CH coupling reactions. To assemble a “copolymer” through homopolymerization, a type of symmetric A‐B‐A‐type building block is designed as the monomer and prepared via the regioselective C5H arylation of thiazole. A PdCl 2 /CuCl‐cocatalyzed oxidative CH/CH homopolymerization has been established to afford the 2,2′‐bithiazole‐based copolymers with high M n (up to 69400). The current protocol features atom‐ and step‐economy and exhibits a potential in the highly efficient construction of conjugated copolymers.
