Both one-pot and two-step procedures for the synthesis of substituted 2-aminothiazoles and 2-aminoselenazoles are described. Anilines are first converted into arenediazonium bromides, which are then reacted with methyl vinyl ketone or cyclopropyl vin

4-Aryl-3-thiocyanatobutan-2-ones were prepared by Meerwein reactions from methyl vinyl ketone and aryldiazonium salts under copper(II) catalysis in 35-75% yields. α-Thiocyanato ketones regioselectively react with 1-methyl-3-aminopyrazole forming
