摘要
三(三甲硅基)环戊二烯基三羰基钼负离子钾盐[{η~5-(Me_3Si)_3C_5H_2}Mo(CO)_3]-Li^+(1),分别与MeI、phCH_2Cl及ClCH_2COOC_2H_5反应生成相应的烃基化钼衍生物[{η~5-(Me_3Si)_3C_5H_2}Mo(CO)_3R],(R=-CH_3,2;-CH_2ph,3;-CH_2COOC_2H_5,4)。1与PCl_3反应除得到预期的钼氯化物[{η~5-(Me_3Si)_3C_5H_2}Mo(CO)_3Cl](5)外,主要得到钼磷氯化物[{η~5-(Me_3Si)_3C_5H_2}Mo(CO)_3PCl_2]6;1与碘反应得到钼碘化物[{η~5-(Me_3Si)_3C_5H_2}Mo(CO)_3I]7;1与HOAc作用后分别和CCl_4、NBS室温反应,仅分离到脱去一个Me_3Si的钼卤化物[{η~5-(Me_3Si)_2C_5H_3}Mo(CO)_3X],(X:Cl,8;Br,9)。
The Lithium salt of tris(trimethylsilyl)cyclopentadienyl tri - carbonyl molybdenum anion Li+[[n5 - ( Me3Si )3C5H2 I Mo ( CO )3 ]- (1), reacted respectively with CH3I, phCH2Cl, and C1CH2COOC2H5 to give the corresponding alkylated molybdenum products [ {n5 - (Me3Si )3C5H2 I Mo (CO)3R],(R:CH3,2;phCH2,3;CH2COOC2H5,4).In the reaction of 1 with PC13, except for a small amount of the expected molybdenum chloride [n5 - (MesSi)3C5H2} Mo(CO)3Cl] (6) , the molybdenum phosphoehloride[{n5 - (Me3Si)3C5H2}Mo(CO)3PCl2](5) became the main product. 1 reacted with iodine to yield the molybdenum iodide [ {n5 - (Me3Si)3C5H2) Mo(CO)3l] (7). 1 was treated with HOAc and followed by the reaction respectively with CCl4 and NBS, only the products - desilylating one of the three silyl groups were afforded [ {n5 - ( Me3Si) 2C5H3} Mo (CO) 3X ], ( X: Cl, 8; Br, 9 ) . The molecular structures of 2 - 6 were characterized by elemental analysis,IR and 1H NMR spectra.
