A new method under metal free conditions has been developed for the direct transformation of N-aryl formamides to corresponding N-aryl carbamates with alcohols using hypervalent iodine reagents as oxidants. The reaction has been postulated to go through the formation of isocyanate intermediates.
在无金属条件下,已开发出一种新方法,可将N-芳基甲酰胺直接转化为相应的N-芳基氨基甲酸酯,使用醇和过氧化碘作为氧化剂。据推测,该反应通过异氰酸酯中间体的形成进行。
