“…As can be seen in Figure 2, the CV curve of 1 c 2+ (black line) features a one‐electron reversible reduction wave (as established using ferrocene as an internal standard, see Figure S7) at E 1/2 =−0.57 V (⊗ E p =80 mV) which fits well with data reported in the literature [13,26,36] . However this result stand in sharp contrast with the electrochemical behavior of others DTE pyridinium derivatives reported in the literature, as dithiazolylethenes, [11,14] which show two reversible reduction waves attributed to the successive formation of mono‐ (DTE .− ) and doubly‐reduced (DTE 2− ) derivatives [14,25] . Similarly, two electron‐reduction waves were seen for the open and closed isomers of DTEs bearing strongly electron‐withdrawing substituents such as benzonitrile [25] …”
