다국어 초록 (Multilingual Abstract)

Direct synthesis of allyldichlorosilane(yield; 37.7％) was investigated by reaction of elemental silicon simultaneously with allyl chloride and hydrogen chloride in the presence of copper catalyst at 260℃. 3-Phenyl-1,1-dichloro-1-silabutane was obtained in good yield(78.2％) by the Friedel-Crafts alkylation of the substituted benzenes with allyldichlorosilane in the presence of aluminum chloride at 0℃ or room temperature. Various monomers(yield: 52∼78％) were synthesized by hydrosilylation of 3-phenyl-1,1-dichloro-1-silabutane with olefins in the presence of hexachloroplatinic acid catalyst. Synthesis and characterization of ladder polymers(yield: 75∼93％) containing silicon atom were investigated.
