“…[79] Recently the terminally bonded phosphinophosphinidene complex [(h 1 -PPtBu 2 ){Cp 2 Zr(PPhMe 2 )}] was reported as the product of reaction between zirconocene dichloride and the reagent tBu 2 P-P(SiMe 3 )Li in the presence of excess [80] The reagent tBu 2 P-P(SiMe 3 )Li joins the tBu 2 P-P= P(X)tBu 2 (X = Br or Me) family as agents effective for the delivery of the PPtBu 2 unit to metal centers, in what has been termed "phosphinophosphinidene transfer". [81][82][83] While earlier reported syntheses proceed by the delivery of an intact {P-PR 2 } fragment to a metal center, our method provides an alternative in that the PÀP bond of the complexed diorganophosphanylphosphinidene ligand is formed by the reaction of the terminal phosphide ion [PNb(NNpAr) 3 ] À with the desired chlorodiorganophosphane, ClPR 2 .…”

Anionic terminal one‐atom nitride, phosphide, and carbide complexes are excellent starting materials for the synthesis of ligands containing low‐coordinate phosphorus centers in the protecting coordination sphere of the metal complex. Salt‐elimination reactions with chlorophosphanes lead to phosphaisocyanide, iminophosphinimide, and diorganophosphanylphosphinidene complexes in which the unusual phosphorus ligands are stabilized by coordination. X‐ray structure analyses and density‐functional calculations illuminate the bonding in these compounds.

XXV [1]Formation and Structure of [{cyclo-P 3 (P t Bu 2 ) 3 }{Ni(CO) 2 }{Ni(CO) 3 }] Abstract. t Bu 2 P±P=P(R) t Bu 2 (R = Br, Me) reacts with [Ni(CO) 4 ] yielding [{cyclo-P 3 (P t Bu 2 ) 3 }{Ni(CO) 2 }{Ni(CO) 3 }]. The two cis-t Bu 2 P substituents of the cyclotriphosphane, which results from the trimerization of the phosphinophosphinidene t Bu 2 P±P, are coordinating to a Ni(CO) 2 unit forming a five-membered P 4 Ni chelate ring. The trans-t Bu 2 P group is linked to a Ni(CO) 3 unit. The compound crystallizes in the orthorhombic space group Pbca (No. 61) with a = 933.30(5), b = 2353.2(1) and c = 3474.7(3) pm.
