Two water soluble1O2 traps: dipotassium 1,3 - diphenylisobenzofuran - 5,6 - dicar☐ylate and tetrapotassium 9,10 - diphenylanthracene - 2,3,6,7 - tetracar☐ylate have been prepared in good yields and a new access to the anthracene skeleton is described. The key-step of this synthesis consists of a cycloaddition between 1,3 - diphenylisobenzofurans and dimethyl 7 - oxabicyclo[2.2.1] - 5 - heptene - 2
