Amines or imides with two strongly electron-withdrawing groups, HNRR´, which are referred to as NH-acids, are popular molecules because they form very weakly coordinating anions. These species are essential components of some olefin polymerization catalysts and lithium-ion batteries. Researchers led by Julius F. Kögel and Jörg Sundermeyer at Philipps University, in Marburg, Germany, have devised a new member of this compound class (shown) that is unprecedented for bearing two different sterically demanding . . .
