“…Polycondensation via Pd-catalyzed SM reaction has emerged as a promising strategy for the synthesis of polymers, which are crucial structures in the development of functional materials and electronic devices. , However, the electrophiles are usually limited to biarylbromides, and the use of biarylchlorides, particularly the most deactivated ones, remains rare . The highly efficient activities of C1 inspired us to explore the versatility of our catalytic system by conducting SM polycondensation using 2,6-dichloropyrazineas electrophiles and 2,7-bis(4,4,5,5-tetraMethyl-1,3,2-dioxaborolan-2-yl)-9,9-di-n-octylfluorene as the coupling partner.…”
