  phosphinimine and borane affording reduction of the phosphinimine to phosphine with concurrent formation of borylamine is proposed. Computational studies were performed to probe the steric effects on these reactions of phosphinimine and borane. Model reactions involving t-Bu(3)PNH showed a lower activation barrier for protonolysis in comparison to phosphinimine reduction. In contrast, for the smaller phosphinimine

• Solution-State Interactions of Bis(pentamethylcyclopentadienyl)ytterbium, Cp*2Yb, with Trialkylphosphines and R3PX Complexes (X = O, NR', CHR'')
  作者：David J. Schwartz、Richard A. Andersen

  DOI：10.1021/om00009a039

  日期：1995.9

  The interactions formed between Cp*Yb-2 (1) and phosphines and R(3)PX derivatives (X = O, NR', CHR'') in solution have been investigated using multinuclear (H-1, C-13, P-31, Yb-171) and variable-temperature NMR spectroscopy. Intermolecular exchange can be slowed at low temperature for 1:1 and 1:2 phosphine adducts, with a (1)J(YbP) value of ca. 950 Hz for Cp*Yb-2(PEt(3)) (3) and Cp*Yb-2(PMe(3)) (4) and ca. 600 Hz for Cp*Yb-2(PMe(3))(2) (2), Cp*Yb-2(dmpm) (dmpm = Me(2)PCH(2)PMe(2)) (5), and Cp*Yb-2(1,2-(PMe(2))(2)C6H4) (6) Adducts of 1 with Me(3)PO and Et(3)PNH undergo slow intermolecular exchange in solution at 25 degrees C (NMR time scale); both 1:1 adducts (Cp*Yb-2(OPMe(3)), 7; Cp*Yb-2(HNPEt(3)), 9) and 1:2 adducts (Cp*Yb-2(OPMe(3))(2), 8; Cp*Yb-2(HNPEt(3))(2), 10) have been isolated. The spectroscopic properties of two ylide adducts, Cp*Yb-2(Me(2)PhPCHSiMe(3)) (12) and Cp*Yb-2(Me(2)LPhPCH(2)) (13), have also been investigated. Intermolecular exchange can be slowed at low temperature in both cases; in the former complex a second process, resulting in inequivalent Cp* rings and inequivalent P-bound methyl groups, can also be slowed at lower temperatures. The nature of this process is discussed in detail. The solid-state structure of 12 has been determined. The NMR values for all of the complexes are discussed in detail. In addition, the Yb-171 chemical shifts for 6, 7, and 12 have been measured, via H-1/Yb-171 indirect detection utilizing long-range J(YbH) coupling, and are discussed.
