“Dance reaction” on the aromatic ring is a powerful method in organic chemistry to translocate functional groups on arene scaffolds. Notably, dance reactions of halides and pseudohalides offer a unique platform for the divergent synthesis of substituted (hetero)aromatic compounds when combined with transition-metal-catalyzed coupling reactions. Herein, we report a tandemreaction of ester dance and

Uni-luminophores of CâN cyclometalated Pt(II) complexes with balanced room temperature fluorescence/phosphorescence dual emission were prepared for ratiometric oxygen sensing in both intensity mode and lifetime mode.
cross-coupling reaction between (hetero)aryl boronic esters and arylsulfides was explored, of which universality was exemplified with thirty small molecules and twelve alternating conjugated polymers. Mechanism studies revealed the importance of room temperature and anhydrous condition in reducing the homocoupling defects and enhancing the optoelectronic properties of the conjugated polymers.
