四甲基二硅桥连双环戊二烯基四羰基二铁与芳香异腈在苯中加热回流生成一个或两个羰基被芳香异腈取代的化合物(Me2 SiSiMe2 )(C5H4 )2 Fe2 (CO)4 -n(CNAr)n [Ar=C6 H5,n =1(1),n =2(2 );Ar=p MeC6 H4 ,n =1(3 ),n =2(4)].单异腈取代化合物 1和 3在二甲苯中加热均可发生热重排反应,生成相应的重排产物(Me2 SiC5H4 )2 Fe2 (CO)3 (CNAr)[Ar=C6 H5(5 ),p MeC6 H4 (6)].通过1HNMR,IR和元素分析表征了化合物 1～ 6的分子结构,并通过X射线衍射分析测定了化合物 3的晶体结构
Tetramethyldisilyl bridged dicyclopentadienyl tetracarbonyl diiron and aromatic isonitrile are heated under reflux in benzene to give one or two compounds (Me2SiSiMe2) (C5H4) 2Fe2 (CO) with one carbonyl group substituted by an aromatic isonitrile. 4 -n (CNAr) n [Ar = C6 H5 n = 1 (1) n = 2 (2) Ar = p MeC6 H4 n = 1 (3) n = 2 The thermal rearrangement reaction of nitrile substituted compounds 1 and 3 in xylene can generate thermal rearrangement reaction, resulting in the corresponding rearrangement product (Me2SiC5H4) 2Fe2 (CO) 3 (CNAr) [Ar = C6H5 (5), pMeC6H4 (6)] The molecular structures of Compounds 1-6 were characterized by1HNMR, IR and elemental analysis, and the crystal structure of Compound3 was determined by X-ray diffraction analysis
