1,2-二环戊二烯基四甲基二硅烷与正丁基锂作用生成(四甲基二硅撑)双[环戊二烯基负离子盐],后者随即与六羰基钼反应即形成1,1′-(四甲基二硅撑)双[环戊二烯基三羰基钼负离子盐],(Me_2SiSiMe_2)[Cp′(CO)_3~-Li~+]_2(1)、1分别与四种不同的卤化物反应,生成在钼原子上发生烃基化的产物(Me_2SiSiMe_2)[Cp′Mo(CO)_3R]_2(R:CH_3,2;C_2H_5,3;=PhCH_2,4;CH_2COOC_2H_5,5).1与林醋酸作用,随即分别与CCl4及NBS反应,生成相应的钼氯化物和钼溴化物(Me_2SiSiMe_2)[Cp′MO(CO)_3X]_2(X:Gl,6;Br,7).1与Fe_2(SO_4)_3/H_3O~+作用发生氧化偶联反应,生成Mo—Mo键双核产物(Me_2SiSiMe_2)[Cp′Mo(CO)_3]_2(8).8在氯仿中与碘反应,又生成Mo—Mo键断裂的钼碘化物(Me_2SiSiMe_2)[Cp′Mo(CO)_3I]_2(9).以元素分析、IR及~1H NMR表征了2—9的结构.并对5的单晶进行了X射线衍射分析.它的晶体属三斜晶系,Pl空间群,晶体学数据:a=1.1447(2),b=1.36(?)0(4),c=1.4125(2)nm;β=60.01(1)~°.V=1.6336nm~3,Z=2,D_o=1.583g·cm~(-2).μ=8.7cm~(-1),F(000)=788.偏差因子R=0.043,R_w=0.055.
1,2-dicyclopentadienyl tetramethyldisilane and n-butyllithium generated (tetramethyldisilazane) bis [cyclopentadienyl anion], which immediately followed by molybdenum hexacarbonyl reaction (1, 1 ’- (tetramethyldisilazane) bis [cyclopentadienyltrimonium molybdate anion], (Me 2 SiSiMe 2) [Cp’ (CO) 3 ~ -Li ~ +] _ 2 Respectively react with four different halides to form the product (Me2SiSiMe2) [Cp’Mo (CO) _3R] _2 (R: CH_3,2; C_2H_5,3; = PhCH_2,4; CH_2COOC_2H_5 , 5) .1 reacted with CCl 4 and NBS respectively to form the corresponding molybdate and molybdate (Cp 2 MO 2) [Cp’MO (CO) 3X] 2 (X: Gl, 7). The oxidative coupling reaction with Fe 2 (SO 4) 3 / H 3 O ~ + resulted in the formation of the Mo-Mo double bond product [Me 2 SiSiMe 2] [Cp’Mo (CO) 3] Molybdenum iodide (Me_2SiSiMe_2) [Cp’Mo (CO) _3I] _2 (9) with Mo-Mo bond was also synthesized. The structure of 2-9 was characterized by elemental analysis, IR and ~ 1H NMR X-ray diffraction analysis of a single crystal with a crystal of triclinic, Pl space group with crystallographic data of a = 1.1447 (2), b = 1.36 (?) 0 (4), c = 1.4125 2) nm; β = 60.0 1 (1) ~ °.
