摘要
五甲二硅基与环戊二烯基羰基过渡金属化合物的金属直接配位的已有不少报道。
The title compound(1)was synthesized by retluxing the xylene solution of cyclopentadienyl pentamethyl disilane and pentacarbonyl iron.1 reacts with iodine to yield the iodinating product 2 with the Fe—Fe bond cleaved.1 was converted to the correspon-ding mono-iron anion by sodium-amalgam reduction.The iron anion reacts with methyliodide and benzyl chloride respectively to give the correspo(?)ding alkylation product 3 and4.The crystal and molecular structure of 1 were determined by X ray diffraction method.The crystals are monoclinic,space group P2_1/a with a=0.7885(1),b=1.1282(2),c=1.8255(2)nm;β=102.85(1)°;V=1.5832nm^3,Z=2,D_c=1.289g.cm^(-3).The R factor is 0.087,R_w is 0.085.
