Access to the first (iminophosphoranyl)(selenophosphoranyl)methane ligands Ph2P(Se)CH2P(NR)Ph2: coordination of their methanide and methandiide anions to ruthenium

Victorio Cadierno, Josefina Díez, Joaquín García-Álvarez and José Gimeno

A family of mixed (iminophosphoranyl)(selenophosphoranyl)methane ligands of general composition Ph2P(Se)CH2P(NR)Ph2 have been synthesized by oxidation of Ph2PCH2P(NR)Ph2 with elemental selenium. In the presence of Et3N, these ligands react with [{RuCl(-Cl)(6-p-cymene)}2] to afford mononuclear Ru(II) species in which the resulting methanide anions adopt a tridentate coordination. Further deprotonation with KH generates carbenic ruthenium derivatives which participate, under remarkably mild conditions, in C–C coupling processes with isocyanides.
