Secondary phosphine oxide-triggered selective oxygenation of a benzyl ligand on palladium

The oxygenation of a benzyl ligand in [PdBnCl(cod)] was dramatically accelerated by using secondary phosphine oxides (SPOs), selectively affording either BnOOH or BnOH, depending on the concentration of O 2 . The SPOs coordinate to palladium in the form of phosphinous acids, operating as Brønsted ac...

Summary:The oxygenation of a benzyl ligand in [PdBnCl(cod)] was dramatically accelerated by using secondary phosphine oxides (SPOs), selectively affording either BnOOH or BnOH, depending on the concentration of O 2 . The SPOs coordinate to palladium in the form of phosphinous acids, operating as Brønsted acids to facilitate further reaction with O 2 . The oxygenation of a benzyl ligand on palladium was dramatically accelerated by using secondary phosphine oxides, selectively affording BnOOH or BnOH.
