A New Approach to Spiroorthocarbonates and New Orthocarbonic Acid Derivatives New and simple processes have been developed, which give in good or excellent yields new diphenoxyalkanediyldioxymethanes, symmetrical and unsymmetrical spiroorthocarbonates, spirocyclic orthothiocarbamic acid esters, and acetals of urea by successive or simultaneous substitution of chloro and phenoxy groups contained in dichlorodiphenoxymethane.
一种针对螺环原碳酸酯的新方法及新型原碳酸衍生物:开发出了新的简单工艺,能够以良好或优异的产率生成新型二苯氧基烷二基二氧亚甲基、对称及非对称螺环原碳酸酯、螺环硫代氨基甲酸酯以及通过连续或同时置换二氯二苯氧甲烷中氯和苯氧基团得到的脲的缩醛。
