## Abstract Bisβiminophosphoranes containing various types of linkers between two R~3~Pο£ΎN 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
Compared with normal and bridge-head aminium cations, the i.riethylenediamine cation is relatively stable. Its ESR specffum shows that the wo nitrogen atoms and all the protons are magnetically equivalent even at 77 K. This f&ours a symmetrical ground state rather than a dynamic equilibrium between
