Orthocarbonates are prepared by a process, comprising:
reacting trichloroacetonitrile with an alkali metal salt or alkaline earth metal salt of an alcohol of the formula:
R—OH (II)
wherein R is an unsubstituted or substituted, saturated aliphatic or cycloaliphatic hydrocarbon radical in which the carbon atom of group R, linked to the oxygen atom of the alcohol, has at least one hydrogen atom, reacting the product obtained in water with an oxidant, extracting the organic-aqueous phase of the material obtained after oxidation, and distilling the extracted material obtained and obtaining orthocarbonate product of the formula:
C(OR)4 (I)
wherein each R group is as defined above.
Orthocarbonates是通过以下过程制备的:将三氯乙酰腈与公式为R—OH(II)的醇的碱金属盐或碱土金属盐反应,其中R是未取代或取代的饱和脂肪族或环烷基碳氢基团,其中R基团的碳原子与醇的氧原子相连,至少有一个氢原子,将在水中得到的产物与氧化剂反应,提取氧化后得到的有机-水相材料,蒸馏提取得到的材料,得到公式为C(OR)4(I)的orthocarbonate产物,其中每个R基团如上所定义。
