【摘要】 从对(三甲硅基)甲苯开始,将苄基中的甲基溴化成溴甲基,从而制得对(三甲硅基)苄基取代的乙酰乙酸乙酯,丙二酸乙酯和氰化物等,应用Sommlet反应制得醛. 将对(三甲硅基)甲苯氧化成相应的羧酸后,用亚硫酰氯处理,加入氨水即得对(三甲硅基)苯甲酰胺.应用类似方法,制得对(三苯硅基)苯甲酸、二甲基二(对羧基苯基)硅烷和二苯基二(对羧基苯基)硅烷的一些酰胺和酯.在用亚硫酰氯处理时,未发现硅-碳键的断裂现象.更多还原

【Abstract】 Starting with p-trimethylsilyltoluene, the methyl group was brominated with N-bromosuc-cinimide into bromomethyl group and thence p-trimethylsilylbenzyl-substituted acetoacetic ester,malonic ester and nitrile were prepared. The bromomethyl group was successfully converted into aldehyde group by means of Sommlet reaction.After the methyl group in p-trimethylsilyltoluene was oxidized into carboxyl group, the amide was prepared through the action of thionyl chloride and ammonia. Similarly, some esters and amides of p-triphenylsilylbenzoic acid, dimethyldi(p- carboxylphenyl) and diphenyldi(p-carboxyl)silane were synthesized. No cleavage of the carbon-silicon bond was found during the thionyl chloride treatment.更多还原
