Fe_2（SO_4）_3／SnCl_4催化合成1，4－二氧螺［4，5］癸烷

Synthesis of 1, 4-dioxaspiro[4, 5]j-decane catalyzed by Fe_2(SO_4)_3/SnCl￣4

使用复合路易斯酸Ｆｅ２（ＳＯ４）３／ＳｎＣｌ４催化合成了１，４－二氧螺［４，５］癸烷，并探讨了合成条件。

Fe2 (SO4) 3/SnCl4 is an effective catalyst for the synthesis of l, 4-dioxaspiro[4, 5] -decane from cyclohexone and ethylene glycol. The synthetic conditions of l, 4-dioxaspiro [4, 5] decane catalyzed by Fe2(SO4)3, Fe2(SO4)3· 10H2O, SnCl4 and Fe2(SO4)3/SnC14 were studied.
