Notes:
Synthesis, redox potentials, and AM1 calculations for 2,3-disubstituted 1,4-benzoquinones 3a-3j are described together with those of N,N′-dicyanimines (DCNQIs) 4. All data compare well with the corresponding 2,5-disubstituted derivatives, except R1,R2 = OMe, SMe. The special effect of these groups is discussed on the basis of low energy out of plane conformers. All DCNQIs 4 occur as syn isomers with respect to the =N—CN groups except 4d, where the five membered ring formed with R1,R2 = -[CH2]3- forms 20% anti-4d in solution. All DNCQIs form CT complexes with TTF (derivatives) with powder conductivities of 10-1 to 10-3 Scm-1.
