The synthesis of arylcyanamides: A copper-catalyzed consecutive desulfurization and C-N cross-coupling strategy
A one pot highly efficient and simple protocol for the construction of aromatic cyanamides from thiourea via desulphurization/C-N cross coupling using a cheap, readily available and air stable copper source as a catalyst has been described. Various iodobenzenes could give their respective C-N cross-coupled products in good to excellent yields under optimized reaction conditions. Further, the substrate scope has been explored.

Novel and green protocol for the synthesis of 2-iminohydantoins
A novel and green protocol for the synthesis of N-1 and C-5 substituted 2-iminohydantoins has been developed. Methyl N-cyano-N-alkyl/aryl-aminoacetate reacts with aqueous ammonia at room temperature in 10-30 min. The developed protocol does not require any work-up for the isolation or purification of the products; simple filtration can lead to the pure products in good to excellent yields.

ANION RECEPTOR, AND ELECTROLYTE USING THE SAME
Disclosed is a novel anion receptor and electrolytes containing the same. A novel anion receptor is an aromatic hydrocarbon compound having an amine substituted with electron withdrawing groups. When the anion receptor is added to the electrolyte, ionic conductivity and cation transference number of electrolytes are enhanced, thereby increasing the electrochemical stability of alkali metal batteries using the electrolytes.
