Abstract Alkyl carbamate (such as 1) reacts with triphosgene at the nitrogen atom, whereas the analogous thionocarbamates (5) react at the sulfur. Subsequent treatment with various phenols or alcohols leads to the corresponding aryl carbamates or alkyl carbamates (6) respectively. The process thus involves both desulfurization and transesterification.
摘要 氨基甲酸烷基酯(如 1)在氮原子处与三光气反应,而类似的硫代氨基甲酸酯(5)在硫处反应。随后用各种酚或醇处理分别产生相应的氨基甲酸芳基酯或氨基甲酸烷基酯 (6)。因此,该过程包括脱硫和酯交换。
