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.

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。
