M. Scholz et al., AN ELECTRON-TRANSFER-INDUCED REACTION-PATH CONTROLLED BY ION-PAIR FORMATION - AN ESR ENDOR STUDY OF FURAN CARBALDEHYDES AND THEIR REACTIVITY, Journal of the Chemical Society, Chemical Communications, (8), 1995, pp. 803-804
When furan 2,5-dicarbaldehyde 1 is single-electron reduced to its radi
cal anion 1(.-) its readiness to couple to give dimer 2 depends upon t
he nature of the ion pair 1(.-)/M+ (M = Li, Na, K, Cs).
