Bis(trimethylsilyl)methanesulfonyl and tris(trimethylsilyl)methanesulfonyl chlorides (2c and 2d, respectively), have been prepared for the first time. Reactions of 2d with nucleophiles give products evidently derived from bis(trimethylsilyl)sulfene (1c). Reaction of 2c with piperidine gives the same piperidide as that from 2d, presumably via 1c formed by dehydrochlorination of 2c, whereas water and
首次制备了双(三甲基甲硅烷基)甲磺酰氯和三(三甲基甲硅烷基)甲磺酰氯(分别为 2c 和 2d)。2d 与亲核试剂的反应得到明显衍生自双(三甲基甲硅烷基)亚砜(1c)的产物。2c 与哌啶的反应产生与 2d 相同的哌啶,推测是通过 2c 的脱氯化氢形成的 1c,而水和氟离子产生的产物与其通过由 2c 形成的三甲基甲硅烷基亚砜(1b)形成的产物一致三甲基甲硅烷基和氯基。没有发现 1c 稳定性增强的证据。关键词:磺酰氯,亚砜,甲硅烷基磺酰氯,甲硅烷基亚砜,脱甲硅烷基化。
