“…Both 6e and 6f show diverse coordination chemistries with Group 11 metals. Bridging P-C-N (6g) [102], 2,2'-bipyridyl diphosphine (6h) [103] and the polyphosphine P-C-N-C-P (6i) [104,105] ligands have also been reported. Tetradentate ligands 6i, based on a phenyl, naphthyl or biphenyl scaffold have been prepared and show (by single crystal XRD) weak C-H .…”

Organophosphorus ligands are an invaluable family of compounds that continue to underpin important roles in disciplines such as coordination chemistry and catalysis. Their success can routinely be traced back to facile tuneability thus enabling a high degree of control over, for example, electronic and steric properties. Diphosphines, phosphorus compounds bearing two separated PIII donor atoms, are also highly valued and impart their own unique features, for example excellent chelating properties upon metal complexation. In many classical ligands of this type, the backbone connectivity has been based on all carbon spacers only but there is growing interest in embedding other donor atoms such as additional nitrogen (–NH–, –NR–) sites. This review will collate some important examples of ligands in this field, illustrate their role as ligands in coordination chemistry and highlight some of their reactivities and applications. It will be shown that incorporation of a nitrogen-based group can impart unusual reactivities and important catalytic applications.
