摘要：

Three isomeric 7,8:17,18-dibenzo[20]annuIene 1,4:11,14-dioxides (V, VI, and VII) have been synthesized by treatment of equimolar portions of 2,5-furandialdehyde and o-xy!ylenebis(triphenylphosphonium bromide) with lithium ethoxide. Irradiation of V, VI, or VII with sunlight led to a fourth, all -trans isomer, VIII. The properties of these four isomers are reported. © 1968, American Chemical Society. All rights reserved.
