Abstract
Abstract N,N'-bis(trifluoromethylsulfonyl)oxamides are described with 2,2,2-trifluoroethyl, (ethoxycarbonyl)methyl, and [(phenylmethoxy)carbonyl]methyl substitution at the amido nitrogen atoms. These compounds, when used in chemiluminescent formulations, furnish superior light capacity and quantum efficiency. Preparation of the compounds and their use for chemiluminescence are described.
