In the presence of a catalytic amount of trityl perchlorate, trimethylsilyl cyanide reacts with the dimethyl acetals of chalcone derivatives, with simultaneous double bond isomerization, to yield γ-methoxy-α,β-unsaturated carbonitriles. Trimethylsilyl sulfides react with dimethyl acetals derived from α,β-unsaturated ketones to yield 1,3-bis(alkylthio)propene derivatives under similar conditions.
在催化量的高氯酸三苯甲基酯存在下,三甲基氰化硅烷与查耳酮衍生物的二甲基缩醛反应,同时进行双键异构化,生成 γ-甲氧基-α,β-不饱和腈。在类似条件下,三甲基甲硅烷基硫化物与衍生自 α,β-不饱和酮的二甲基缩醛反应生成 1,3-双(烷硫基)丙烯衍生物。
