The present invention provides a process for producing a variety of unsaturated carbamic acid derivatives from corresponding unsaturated carbamates by substitution reaction. The present invention provides a process for producing unsaturated carbamic acid derivatives, comprising reacting an unsaturated carbamate represented by <CHEM> wherein R represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, R<1> represents a residue of an alcohol from which an OH group is removed, with an alcohol, a primary or secondary amine or an oxime at a temperature of 80 to 150 DEG C to substitute the -OR<1> group in the formula (A). |
