The palladium-catalyzed coupling reaction of these stannanes with aryl iodides yield functionalized phosphines in high yield (69–97%). The use of Ph3P as starting reagent, the endurance of the reaction to a wide variety of functional groups and the easiness of a one-pot reaction make this method a useful and versatile approach to tertiary phosphine oxides.The palladium catalyzed reaction of several iodoarenes with Me3SnPPh2, prepared from the reaction of Me3SnCl with Ph2P− ions gave good yields of aryldiphenylphosphines (isolated as the oxides) in a one pot procedure.
