  Formation of Novel P-Functionalized Ligands by Insertion Reactions of RNCX (R = Ph, X = O, S; R = Prⁱ, X = O) into the Zr−P Bond of [Cp°₂ZrCl(PHCy)] (Cp° = η⁵-C₅EtMe₄, Cy = Cyclohexyl) and [Cp‘₂ZrCl{PH(TRIP)}] (Cp‘ = η⁵-C₅MeH₄, TRIP = 2,4,6-Prⁱ₃C₆H₂)

  摘要：

  [Cp degrees(2)ZrCl(PHCy)] (1; Cp degrees = eta(5)-C5EtMe4, Cy = cyclohexyl) and [Cp'2ZrCl{PH(TRIP)}] (2; Cp' = eta(5)-C5MeH4,TRIP = 2,4,6-(Pr3C6H2)-C-i) readily insert RNCX (R = Ph, X = S, O; R = Pr-i, X = O) to give [Cp degrees(2)ZrCl{eta(2)-XC(PHCy)NR}] (X = S, R = - Ph (3); X = O, R = Ph (4); X = O, R = Pr-i (5)) and [ Cp'2ZrCl{eta(2)-XC{PH(TRTP)}NR}] (X = S, R = Ph (6); X = O; R = Ph (7); X = O, R = Pr-i (8)). 3-8 were characterized spectroscopically (IR, NMR, MS), and crystal structure determinations on 4-6 showed an eta(2) bonding mode (X,N) of the XC(PHR')NR (R' = Cy, TRIP) ligands. Of the two possible coordination modes of the ligand, 4 and 5 are obtained exclusively as the endo isomer, in which the NR group is adjacent to the Zr-Cl bond, while for 6-8, both isomers (endo and exo) are formed (1:8 (6), 1:30 (7) and 1:5 (8)), whereby the exo isomer is favored. The exo isomer of 6 was structurally characterized.

When the reaction with LiPHMes is carried out in a 1:1 ratio, cis-[Cp*TaCl(μ-PMes)}2] (4a) is also formed besides 4b.

  the triple-decker complex [(Cp*Fe)(Cp’’’Co)(μ,η5 : η4-P5)] show that the reaction with main group nucleophiles yields different products depending on the steric demand of the nucleophile used. Subsequent oxidation/electrophilic quenching provides a plethora of P5R2 and P6R3 organophosphorus ligand complexes in unique 1,3 or 1,4 substitution pattern as opposed to the parent complex [Cp*Fe(η5-P5)].
