Synthesis, reactivity and antimicrobial activity of a series of 2-arylamino-1,3-selenazoles
A series of 2-arylamino-1,3-selenazoles was synthesized and their reactivity was studied. The 2-arylamino-1,3-selenazoles and their reaction products were characterized by various spectroscopic methods and X-ray diffraction. In addition, the antimicrobial

A novel and convenient synthesis of 3-amino-2H-1,2,4-triazoles from isoselenocyanates and hydrazine hydrate
A novel and convenient one-pot synthesis of 3-amino-2H-1,2,4-triazoles from two molecules of isoselenocyanates and hydrazine hydrate via cyclodeselenisation was developed. Various 3-amino-2H-1,2,4-triazoles were obtained in moderate to good yields (33-45%
Synthesis of cyanamides from isoselenocyanates promoted by recyclable ionic liquid-supported (diacetoxyiodo)benzene
One-pot synthesis of cyanamides from isoselenocyanates through deselenisation promoted by ionic liquid-supported hypervalent iodine(III) reagent 1-(4-diacetoxyiodobenzyl)-3-methylimidazolium tetrafluoroborate [dibmim BF4 was developed. This approach provided a simple, mild and environmentally benign way to construct cyanamides in good yields. Moreover, powder Se and dibmim + BF4 could be easily recycled. It was the first example of [dibmim] + [BF4- to be used as a deselenising agent.
