Differential radical cation stability from the cis- and trans-cyclodiphospha(III)azane derivatives

The electrochemical oxidation reactions of cis-and trans-1,3-di-isopropyl- 2,4-bis(di-isopropylamino)-cyclodiphospha(III)azane isomers are quite different; only the trans-(1) isomer undergoes a one-electron oxidation reaction to produce a stable radical cation.
