New facial amidophosphine ligands: Construction and applications

Amido(bis)phosphines that bind facially to transition metals represent a logical design iteration that offers coordination properties distinct from those of tris(phosphino)borates already studied by our group. Chief among these new properties are the electronic effects resulting from a coordinating hard amido donor, esp. via possible pi donation. A general synthetic scheme that allows parallel variation of functional groups at the N and P donors has been developed, and preliminary coordination chem. is presented and discussed.
