  Transformation of Acyclic Alkenes to Hydrido Carbynes by (PNP^R)Re Complexes

  摘要：

  Synthesis of (PNPR)ReOCl2 (PNPR = (R2PCH2SiMe2)(2)N, R = Pr-i, Cy, and Bu-t) from (Me2S)(2)-ReOCl3 and (PNPR)MgCl is described. Magnesium and H-2 convert (PNPR)ReOCl2 first to (PNPR)ReO(H)(2) and then to (PNPR)Re(H)(4), the last being an operationally unsaturated species which can bind PMe3 or p-toluidine. Acyclic alkenes react with (PNPR)Re(H)(4) at 22 degreesC to give first (PNPR)Re(H)(2)(olefin) and then (PNPR)ReH(carbyne), in equilibrium with its eta(2)-olefin adduct. Re can also migrate to the terminal carbon of internal olefins to form a carbyne complex. Allylic C-SiMe3 or C-NH2 bonds are not broken, but OEt, OPh, and F vinyl substituents (X) are ultimately cleaved from carbon to give the Reequivalent toC-CH3 complex and liberate HX. DFT calculations, together with detection of intermediates for certain olefins, help to define a mechanism for these conversions.
