Reactions of the title compound (I) with O2 or CO gave anthracene. 9,10-Dihydroanthracene was obtained in reactions of I with H2 or CHYCH in THF. With CO2, 9,10-dihydroanthracene-9,10-dicarboxylic acid II (R = R1 = CO2H) was obtained in 82% yield. With Me2CO, dihydroanthryldimethylcarbinol II (R = Me2COH, R1 = H) was obtained in 64% yield. Reaction of I with EtBr gave diethyldihydroanthracene II (R = R1 = Et) in 99% yield.
