• state. We thought that radialenes would be an attractive candidate as a ligand and would exhibit a facile haptotropic rearrangement when coordinated to Pt(dpe). The LUMO is all-in phase combination of olefinic π* as shown for 6-radialene by 23 in Figure 7. Therefore, the ML2 b2 fragment would retain a

The pioneering studies on the synthesis of tetrakis(1,3-dithiol-2-ylidene)cyclobutane (8) and related [5] and [6]radialenes 9 and 10a,b were reported by Yoshida and co-workers in the 1980’s (Figure 4). These π-expanded TTFs 8–10a,b

Compound 3 is considerably more electron deficient than previously reported hexaaryl[3]radialenes, with reduction potentials of −0.06 and −0.45 V in CH2Cl2. The compounds mostly display red fluorescence with large Stokes shifts. Keywords: anion–π interactions

Such compounds display
