Electron Transfer in Reaction of 12H-Quinoxalino[2,3-b]phenoxazines with π-Acceptors

Abstract

Using the reaction of 2,4-di-(tert-butyl)-12-(4-methoxyphenyl)-10-methoxy-12H-quinoxalino[2,3-b]phenoxazine with π-electron acceptors such as tetracyanoquinodimethane and 3,6-di-(tert-butyl)-o-quinone) as an example it was shown that derivatives of this N,O-pentaheterocyclic system are effective electron donors that, under mild conditions, carry out electron transfer reactions with the formation of stable cation and anion radical structures.
