Unsymmetrical bidentate ligands R2P (E)–N (H)–P (E′) R2′[R, R′= Ph, OPh, iPr; E, E′= O, S, Se] have been synthesised using the condensation reaction of an amino compound, R2P (E) NH2 [R= PhO, Ph; E= O, S, Se], with a phosphorus electrophile, R2′ P (E′) Cl [R′= iPr, Ph, OPh; E′= O, S, Se]. Deprotonated ligands (with KOtBu) can be treated with Pd (OAc) 2 to give [Ph2P (S)–N–P (O)(OPh) 2] 2Pd,[iPr2P (S)–N–P (O)(OPh) 2] 2Pd and [ ...
