In the presence of a Lewis-acid catalyst, such as HgCl2 or ZnCl2, cyclohexyl isocyanide reacted with chlorine and tetrahydrofuran to give, after hydrolysis, 4-chlorobutyl cyclohexylcarbamate in a fair yield. When one of the reactants was replaced by another isocyanide, bromine, or another cyclic ether, the reactions proceeded similarly, but the corresponding carbamate yields were rather poor.
在
路易斯酸催化剂(如HgCl2或ZnCl2)的存在下,
环己基异氰酸酯与
氯和
四氢呋喃反应,经过
水解后,得到了4-
氯丁基
环己基氨基甲酸酯,产率相当可观。当其中一个反应物被另一个
异氰酸酯、
溴或另一种环状醚替换时,反应仍然类似进行,但相应的
氨基甲酸酯产率则相对较低。
