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.

An efficient "one-pot" approach to multiple substituted ureas from N-arylcyanamide and diaryliodonium salts has been presented. The two-step procedure involved the weak base-promoted chemoselective arylation of secondary amines with diaryliodonium and Cu-catalyzed nucleophilic addition of N-arylcyanamide with second diaryliodonium. The diverse unsymmetrical arylureas were obtained in up to 91% yield for 29 examples.

A series of N,N'-diphenyl and N-naphthyl-N'-phenyl guanidine derivatives was synthesized as potential N-methyl-D-aspartate (NMDA) receptor positron emission tomography (PET) ligands. The affinity of the different compounds was determined using in vitro receptor binding assays, and their log P values were estimated using HPLC analysis. The effect of N'-3 and N'-3,5 substitution on affinity and lipophilicity was examined. The K(i) values ranged from 1.87 to 839nM, while log P values between 1.22 and 2.88 were observed.
