The substituted phosphorus fluorides (CH₃)₂NPF₂, (C₂H₅)₂NPF₂, and C₅H₁₀NPF₂ (C₅H₁₀ = piperidyl) have been prepared by fluorinating the corresponding chlorides R₂NPCl₂ with SbF₃ or a suspension of NaF in tetramethylene sulfone. These substituted phosphorus fluorides serve as interesting ligands which will displace CO from nickel and molybdenum carbonyls to give compounds of the type Ni(CO)₂L₂, NiL₄, and Mo(CO)₃L₃ (L is any of the new fluorides).
