Divergent Synthesis of 2,5-Diarylphospholes Based on Cross-coupling Reactions: Substituent Effects on the Optical and Redox Properties of Benzene–Phosphole–Benzene π-Systems
Divergent Synthesis of 2,5-Diarylphospholes Based on Cross-coupling Reactions: Substituent Effects on the Optical and Redox Properties of Benzene–Phosphole–Benzene π-Systems
Divergent synthesis of 2,5-diarylphosphole derivatives was achieved by using two kinds of Pd-catalyzed cross-coupling reactions. In addition, para- and P-substituent effects on the optical and redox properties of the benzene–phosphole–benzene π-systems were disclosed experimentally.
