Abstract We herein report a metal‐free strategy for the selective synthesis of xanthenes and xanthones from 2‐aryloxybenzaldehydes. By employing phosphorous acid/iodine system, we achieved efficient preparation diverse via intramolecular reductive cyclization. In contrast, series were constructed same substrates through TBAI‐catalyzed direct This methodology offers notable advantages, including straightforward workup, absence metal involvement, low‐cost. A plausible reaction mechanism was also proposed.

Herein, we report a both regioselective and stereoselective method for the formation of C(sp2)–P bonds using alkenylsulfonium salts >P(O)–H compounds. By employing palladium catalyst or K2CO3, variety (E)-alkenylphosphorus compounds terminal alkenylphosphorus were successfully synthesized with high selectivity. Notably, trisubstituted (Z)-alkenylphosphorus first time under metal-free conditions. This protocol has wide substrate scope good functional group compatibility, providing direct highly selective approach preparation various
