                                    Sulphonium bismethoxycarbonylmethylides react with acids by a pummerer-type reaction and by nucleophilic substitution on sulphonium salts formed by protonation of the ylides; the product distributions depend on both the ylides and acidity of solvents.
                                    双甲氧基羰基甲基ul通过pummerer型反应和亲核取代由ides离子质子化形成的sulph盐与酸反应;产物分布取决于溶剂的酰基化物和酸度。
