Reaction Steps

For example, 5,6,7,8-tetrafluoro-9,10-dihydroxy-2,3-dihydroanthracen-1,4-dione (1) is reacted with 4,5,6,7-tetrafluoroisobenzofuran-1,3-dione (2) to give 1,2,3,4,8,9,10,11-octafluoro-5,7,12,14-tetrahydroxypentacen-6,13-dione (3) (scheme 5). In addition, 5,7,12,14-tetrahydroxypentacen-6,13-dione (6) can be obtained from 9,10-dihydroxy-2,3-dihydroanthracen-1,4-dione (4) and isobenzofuran-1,3-dione (5) (scheme 6).
