摘要
报导了用无水氯化钙为催化剂合成1，4－H氧杂螺[4．5]癸烷的新方法，探讨了该缩合反应条件。结果表明，无水氯化钙是该缩会反应的优良催化剂，1，4-二氧杂螺[4．5]癸烷收率较高。
The present article reportsthe new synthetic method of 1, 4 - dioxaspiro[4. 5] decane for cata lyst by anhydrous calcium chloride ,and investigates the conditions of this condensation reaction . The results indicate that anhydrous calcium chloride is a better catalyt in this condensation reachon, and to get higher yeild for 1,4 - dioxaspiro[4.5]decane.
