J Am Chem Soc. 2007 Apr 25;129(16):5180-7. Epub 2007 Mar 28. Treatment of oxo and imido-rhenium (V) complexes Re (X) Cl3 (PR3) 2 (X = O, NAr, and R = Ph or Cy) (1-2) with Et3SiH affords Re (X) Cl2 (H)(PR3) 2 in high yields.

J Phys Chem A. 2008 Mar 6;112(9):1946-55. Epub 2008 Feb 13. Chemically reasonable models of PR3 (R = Me, Et, iPr, and tBu) were constructed to apply the post Hartree-Fock method to large transition metal complexes. For more bulky phosphine, the SRC is important to present correct energy change, in which the MP2 method presents reliable steric repulsion correction like the CCSD (T) method because the systems calculated in the SRC do not include a transition metal element. |

Addition of ethoxalyl (ClCOCOOEt) to terminal alkynes at 60 degrees C in the presence of a rhodium (I)-phosphine complex catalyst chosen from a wide range affords 4-chloro-2-oxo-3-alkenoates regio- and stereoselectively. The oxidative addition of ethoxalyl to [RhCl (CO)(PR (3))(2)] proceeds readily at 60 degrees C or room temperature and gives [RhCl (2)(COCOOEt)(CO)(PR (3))(2)] (PR (3) = PPh (2) Me, PPhMe (2), PMe (3)) complexes in high yields. |

In D2O in the presence of HCl, THPP reversibly attacks the -C atom to form the (alpha- phosphonium derivative [PhCH=C (H) CH (OD) PR3] Cl (where R=(CH2) 3OD), which slowly converts into the deuterated bisphosphonium salt [R3PCH (Ph) CD (H) CH (OD) PR3] Cl2 via the deuterated monophosphonium salt [R3PCH (Ph) CD (H) CHO] Cl. |

Similarly, reactions of R (t-Bu)(2) PNH (R = n-Bu, t-Bu) and i-Pr (3) PNH with pinacolborane (HBO (2) C (2) Me (4) = HBpin) led to the formation of n-Bu (t-Bu (2)) PNBpin, t-Bu (3) PNBpin, and i-Pr (3) PNBpin. Analogous reactions of smaller phosphinimines R (3) PNH (R = Et or n-Bu) with pinacolborane (HBpin) generated free phosphine and the -containing product HN (Bpin)(2). |
