Abstract:
A method for producing N-(2-amino-1,2-dicyanovinyl)formamidine, including the steps of reacting an N-(2-amino-1,2-dicyanovinyl)formimidate and ammonia by adding aqueous ammonia to a solution or suspension of an N-(2-amino-1,2-dicyanovinyl)formimidate in ether, or alternatively directly adding an N-(2-amino-1,2-dicyanovinyl)formimidate or adding a solution or suspension of an N-(2-amino-1,2-dicyanovinyl)formimidate in ether to a liquid containing ether and aqueous ammonia.
