【摘要】 本文报道了二茂锆氢化物与异氰酸酯在不同条件下的反应。Cp₂Zr（H）Cl与RNCO(R=C₆H₅,α-C₁₀H₇)在苯中,5～10℃下反应,生成锆的氧桥络合物（Cp₂ZrCl）₂O（1）和Schiff碱型化合物RN=CH₂(2:R=C₆H₅;3:R=α-C₁₀H₇)。当反应在25～30℃下进行时,还有少量有机胺RNH（CH₃）及很少量的RNHCONHR生成。而（Cp₂ZrH₂）_?与RNCO反应时,同时发生加成和脱氧两种反应,生成双齿配位络合物Cp₂Zr（H）[RN=C（H）=O](4:R=C₆H₅;5:R=α-C₁₀H₇)和化合物（Cp₂ZrO）₃（6）、RNH.（CH₃）(7:R=C₆H₅;8:R=α-C₁₀H₇)及少量未知化合物。产物经元素分析、IR、¹H及¹³C NMR和GC-Ms谱分析鉴定。更多还原

【Abstract】 Oxygen-bridging zirconocene complex（Cp₂ZrCl）₂O（1）and Schiff baseproducts RN=CH₂（2:R=C₆H₅;3:R=α-C（10）H₇）were formed by reactions of Cp₂Zr-（H）Cl with phenyl-and α-naphthyl-isocyanate in C₆H₆ at 5～10℃.At 25～30℃,amines RNH（CH₃）and a very small amount of RNHCONHR were also formed.Ho-wever,when（Cp₂ZrH₂）_x reacted with phenyl-and α-naphthyl-isocyanate both additionand deoxygenation reactions took place and yielded bidentate complexes Cp₂Zr（H）[RN=C（H）=O](4:R=C₆H₅:5:R=α-C₁₀H₇),compounds（Cp₂ZrO）₃（6）,RNH（CH₃）(7:R=C₆H₅;8:R=α-C₁₀H₇)and an unknown compound.These products were identifiedby elemental analyses,IR,¹H &¹³C NMR and GC-MS spectra.the differencesbetween these two reactions and the reaction mechanisms were studied.更多还原
