Transition-Metal-like Behavior of Main Group Elements: Ligand Exchange at a Phosphinidene

(Phosphino)­phosphaketenes (>PPCO) behave as (phosphino)­phosphinidene-carbonyl adducts (>PP←:CO). CO scrambling was observed using 13C labeled CO, and exchange reactions with phosphines afford the corresponding (phosphino)­phosphinidene–phosphine adducts (>PP←:PR3). The latter react...

Description
Summary:(Phosphino)­phosphaketenes (>PPCO) behave as (phosphino)­phosphinidene-carbonyl adducts (>PP←:CO). CO scrambling was observed using 13C labeled CO, and exchange reactions with phosphines afford the corresponding (phosphino)­phosphinidene–phosphine adducts (>PP←:PR3). The latter react with isonitriles and singlet carbenes giving (phosphino)­phosphinidene–isonitrile (>PP←:CNR) and −carbene adducts (>PP←:C
