摘要
研究了溶剂对硝酸铵催化的2,10-环氧蒎烷液相重排反应的影响.重点考察了催化剂在不同溶剂中的溶解性及溶剂对重排产物分布的影响.结果表明:硝酸铵难溶于硝基甲烷、氯仿而易溶于DMF,溶剂的极性、酸碱性和形成氢键的特性对重排产物分布有显著的影响.
The effects of solvent on NH4 NO3 -catalyzed liquid-phase rearrangement of 2, 10-epoxy-pinane were studied in this paper. The solubility of ammonium nitrate in different solvents and the influence of solvent on the product distribution were investigated. Experimental results indicated that NH4 NO3 is immiscible in nitromethane and chloroform, but miscible in N, N-dimethylformamide. The effects of the polarization, acidity and the character to form hydrogen bond on the product distributions of the rearrangement reaction are significant.
