摘要: 以3-乙基-3-羟甲基氧杂环丁烷为原料,与甲基磺酰氯磺酰化,得到3-乙基-3-甲磺酰基甲基氧杂环丁烷;在碱性条件下,以PEG600作相转移催化剂,用3-乙基-3-甲磺酰基甲基氧杂环丁烷与乙二醇醚化得到2-[(3-乙基-3-氧杂环丁基)甲氧基]乙醇;然后与甲基丙烯酸甲酯进行酯交换得到目的产物2-[(3-乙基-3-氧杂环丁烷)甲氧基]甲基丙烯酸乙酯。3-乙基-3-羟甲基氧杂环丁烷与3-溴丙烯反应,生成3-乙基-3-[(2-丙烯-1-基氧基)甲基]氧杂环丁烷,然后在氯铂酸的催化下,与三乙氧基硅烷反应得到3-乙基-3-[[3-(三乙氧基硅)丙氧基]甲基]氧杂环丁烷。产物经红外光谱和核磁共振谱表征得到确证。

Abstract: 3-Ethyl-3-methanesulfonylmethyloxetane, which was prepared from the reaction of 3-ethyl-3-hydroxymethyloxetane with methylsulfonyl chloride, reacted with ethylene glycol under alkaline conditions and PEG600 as a phase transfer catalyst to give 2-[(3-ethyl-3-oxetanyl)methoxy]ethanol. Then 2-[(3-ethyl-3-oxetanyl)methoxy]ethanol reacted with methyl methacrylate to give the target compound of 2-[(3-ethyl-3-oxetanyl)methoxy]ethyl methacrylate. 3-Ethyl-3-[(2-propen-1-yloxy)methyl]oxetane, which was prepared by the reaction of 3-ethyl-3-hydroxymethyloxetane with 3-bromopropene reacted with triethoxysilane under catalysis of chloroplatinic acid to give 3-ethyl-3-[3-(triethoxysilyl)propoxy]methyl]oxetane. The structure of title compounds were identified by IR and 1HNMR spectrum.

Key words: 2-[(3-ethyl-3-oxetanyl)methoxy]ethyl methacrylate, 3-ethyl-3-[3-(triethoxysilyl)propoxy]me-thyl]oxetane, cationic curing
