摘要: 本文以5-叔丁基呋喃甲酸铬(Ⅲ)和三氯化铝作催化剂,使乙酰氧基硅烷和环氧化物,在均相或非均相条件下反应,得到了相应的开环加成产物——取代硅氧丙基乙酸酯。实验结果表明,在本文的两种实验条件下,使用5-叔丁基呋喃甲酸铬(Ⅲ)作催化剂比用三氯化铝更为有效。

Abstract: Ring cleavage reaction between alkyl (aryl) acetoxysilanes and epoxides using 5-tert-butyl-2-furanatochromium (III) and aluminium chloride as catalysts was studied and the corresponding products substituded siloxy-propyl acetate were obtained. Experimental results show that it is more advantageous in the two experimental routes to make use of 5-tert-butyl-2-furanatochromium (III) than alumium chloride.
