✦ Synopsis
redox potentials, and AM1 calculations for a series of 2,3-disubstituted 1,4benzoquinones, e.g. (I), are described together with those of the corresponding N,N'-dicyanimines (II). All data compare well with the corresponding 2,5disubstituted derivatives, except for those with methoxy and methylthio groups. The special effect of these groups is discussed on the basis of low energy out of plane conformers. All compounds (II) occur as syn isomers with respect to the cyanimine groups except (IIc) where 20% anti (IIc) is formed in solution. All (II) form CT complexes with tetrathiofulvalene (derivatives) with powder conductivities of 10 -1 to 10 -3
