Project

From simple precursors to unprecedented heterocyclic systems containing heavier Group 15 elements (GA18-10222S)

the pnictogen is stabilized within unprecedented heterocyclic systems. These compounds will be investigated with the aim to synthesize other heterocyclic compounds that have not been of these heterocycles. The structure of...
