MONOARYLATION OF DIPHENYLDITHIENYLETHENE BY LIGAND-FREE PALLADIUM CATALYZED C-H ACTIVATION

Tóm tắt

This work reports on a green and convenient methodology for the arylation of diphenyldithienylethene by direct ligand-free palladium-catalyzed C–H bond functionalization. Based on this approach, a new diphenyldithienylethene-based compound with aryl substituent DTE-3-CHO-1 was successfully synthesized from thiophene via 4 steps. These compounds were structurally identified by NMR and HR-MS spectral analyses.
