New Access to Six‐Membered Phosphacycle Annulated Polyaromatic Ring System

A facile Ag‐catalyzed intramolecular C–P bond formation reaction from easily accessible phosphine oxides has been developed. Several new heteroatoms fused π‐conjugated molecules were synthesized from this procedure with their structures confirmed by X‐ray structure analyses. A facile access to six‐m...

Zusammenfassung:	A facile Ag‐catalyzed intramolecular C–P bond formation reaction from easily accessible phosphine oxides has been developed. Several new heteroatoms fused π‐conjugated molecules were synthesized from this procedure with their structures confirmed by X‐ray structure analyses. A facile access to six‐membered phosphacycle annulated polyaromatic ring system through Ag‐catalyzed intramolecular C–P bond formation reaction, from easily accessible phosphine oxides, has been developed, Several new heteroatoms fused π‐conjugated molecules were synthesized from this procedure with their structures confirmed by X‐ray structure analysis.
