The synthesis of the novel 5-amino-8-phenyl-3H,6H-1,4,5a,8a-tetraazaacenaphthalen-3-one ring system has yielded several compounds which display activity in the reversal of cognition deficits in rats and mice as compared to existing reference agents.

A new highly efficient class of chemiluminescent oxalic acid derivatives, N-trifluoromethyl sulfonyl oxamides, has been discovered. One member of this class, N,N'-bis(2,4,5-trichlorophenyl)-N,N'-bis(trifluoromethylsulfonyl) oxamide, has given the hig
