Abstract
The highly charged tetraanion of the unsubstituted p-bistyrylbenzene (1) an d the hexaanion of 1,3,5-tristyrylbenzene (4) were generated and studied in vacuo at low temperatures. The various reduction steps were followed by UV and several NMR techniques. Extensive folding resulting from quinoid forms , determined to exist in the dianion of p-bistyrylbenzene, 1(2-), are absen t in the highly charged tetraanion 1(4-).
