The purple‐coloured iron peroxo complex [Fe(III)EDTA(η2‐O2)]3− as a novel reagent system for Pd‐catalyzed decarboxylative ortho‐acylation of acetanilides with α‐oxocarboxylic acids at roomtemperature in aqueous media has been realized. This reaction provides an effective access to ortho‐acylacetanilides under mild conditions.

A highly enantio- and diastereoselectivehydrogenation of congested tetra-substituted β-enamido phosphorus derivatives was developed by employing commercially available Rh-Josiphos as the catalyst. This protocol offers a straightforward entry to a broad variety of previously difficult-to-access chiral β-amino phosphonates/phosphine oxides bearing two vicinal stereocenters embedded in various ring structures
