一种高效制备4,4-二甲基-3,5,8-三氧杂双环[5,1,0]辛烷的方法
摘要：
本发明公开了一种高效制备4,4-二甲基-3,5,8-三氧杂双环[5,1,0]辛烷的方法，以4,7-二氢-2,2-二甲基-1,3-二氧杂环庚-5-烯为原料，在催化剂和过氧化氢的存在下，反应生成4,4-二甲基-3,5,8-三氧杂双环[5,1,0]辛烷，所述催化剂选自磷钼酸、磷钨酸、钨酸钠和乙酰丙酮氧钒。根据本发明的方法能够显著降低反应温度，避免了大量废物的产生，极大地提高了产物的纯度。
摘要（英）：

The invention discloses a method for efficiently preparing 4,4-dimethyl-3,5,8-trioxabicyclo[5,1,0]octane. According to the method, 4,7-dihydro-2,2-dimethyl-1,3-dioxep-5-ene is used as a raw material and is subjected to a reaction in the presence of a catalyst and hydrogen peroxide so as to produce 4,4-dimethyl-3,5,8-trioxabicyclo[5,1,0]octane, wherein the catalyst is selected from the group consisting of phosphomolybdic acid, phosphotungstic acid, sodium tungstate and vanadyl acetylacetonate. The method of the invention can significantly reduce reaction temperature, avoid the generation of a large amount of waste, and greatly increase the purity of the product 4,4-dimethyl-3,5,8-trioxabicyclo[5,1,0]octane.
