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.
