Abstract
As a result of checking suited methods for preparing N,N-disubstituted 2-amino-selenazoles 14 as a nearly unknown class of highly reactive selenazoles a simple route starting from N,N-disubstituted selenoureas 12 has been elaborated and used for the synthesis of a series of these compounds. The necessary selenium-containing starting compounds 12 are available from N,N-disubstituted cyanamides 18 and hydrogen selenide.
