  摘要：

  Treatment of dicyanophosphines R-P(CN)(2) with 1 equiv of Schwartz's reagent, [Cp2Zr(H)Cl](n), led: (i) via a substitution reaction to the formation of the stable hydrocyanophosphines R-P(H)CN (R = Me, Bu-t, Mes*) or (ii) through a hydrozirconation reaction to the synthesis of the aldiminocyanophosphine R-P(CH=NZrCp2Cl)CN (R = (NPr2)-Pr-i). Further addition of 1 equiv of [Cp2Zr(H)Cl](n) to R-P(H)CN (R = Me, Bu-t, Mes*) gave the primary phosphine R-PH2 (R = Me) or the aldimino secondary phosphine R-P(H)(CH=NZrCp2Cl) (R = Bu-t, Mes*) after the hydrozirconation reaction. Interestingly, the dialdiminophosphorus compound R-P(CH=NZrCp2Cl)(2) (R = (NPr2)-Pr-i) was obtained after addition of [Cp2Zr(H)Cl](n) to R-P(CH=NZrCp2Cl)CN (R = (NPr2)-Pr-i). The difference in reactivity observed for the dicyanophosphines R-P(CN)(2) with the metal hydride [Cp2Zr(H)Cl](n) have been studied with the help of experimental analysis (UV-photoelectron spectroscopy, NMR, IR, X-ray) and computational methods.
