摘　　要：以四烯丙基硅烷(G0)为核心制备了第一代(G1)和第二代烯丙基硅烷(G2).产物以正己烷-乙酸乙酯V(正己烷)∶V(乙酸乙酯)=20∶1为流动相,采用一次硅胶柱层析法,用薄层层析(TLC)检测,成功脱除杂质,目标产物收率为67.6%(G1)和64.8%(G2).经核磁共振、热质量分析等表征提纯产物,表明目标产物结构完整.The allylsilanes of the first generation （ Gj ） and the second generation （ G2 ） were prepared by using tetra-allylsilane （Go ） as a main material. The synthesized products were purified by the column chromatography with the hexane/ethyl acetate hybrid solvent （V（hexane） ： V（ ethyl acetate） = 20：1 ） as the mobile phase. The component yield was 67.6% for G1 and 64.8% for G2, respectively. The thin layer chromatography was used as a auxiliary detection method. The purified products were characterized by ^1H NMR and TGA（thermogravimetric analysis）. Results showed that the key components had integral anticipated structures.
