Abstract
Diazonium salts obtained from aminophenyl-substituted crown ethers react with paramagnetic imidazolinium salt to yield arylazoenamines, containing spin-labeled crown ethers. An alternative approach to the synthesis of related compounds, spin-labeled ureas, consists of the reaction of aminophenyl-substituted crown ethers with paramagnetic isocyanates.
