## Abstract Bis‐iminophosphoranes containing various types of linkers between two R~3~PN moieties were electrochemically oxidized at controlled potential __in situ__ in the electron spin resonance (ESR) cavity. For linkers constituted of phenylenes, conjugated phenylenes or merely a dicyanoethylen
I4N-and 'H-Coupling constants, determined by ESR, ENDOR, and general-TRIPLE-resonance spectroscopy, are reported for the radical cations of tetrazinodi(heteroarenes) 1-8. The results comply with the expectation that donor properties of these compounds are mainly due to the electron-rich dihydrotetra
Phenothiazines are of interest as model heterocyclic compounds and also as pharmacological agents with a wide spectrum of biological activities. Cation radicals derived from six phenothiazine derivatives including phenothiazine, 2-chlorophenothiazine, promazine, chlorpromazine, promethazine and trim
