摘要
研究合成多种缩醛并对相应缩醛进行裂解试验,试验表明:烯醛缩合的得率随羰基碳原子所带正电量的增加而呈直线增加;相应缩醛的裂解产物中烯醛的得率与二氧环戊烷所连碳碳键的长度呈负相关。
The synthesis and the pyrolysis of several unsaturated acetals are investigated. We find the yield of acetal increases linearly with the increase of atomic charge of the carbon of the carbonyl; while the yield of the enals in pyrolysis products decrease with the increase of the length of C-C bond which is connected to the dioxolane.
