Synthesis of Benzo-Fused Tetraphenylenes and Crystal Structure of a 4:1 Clathrate Inclusion Compound of Dibenzotetraphenylene with p-Xylene

Article abstract of DOI:10.1021/jo00297a043

Benzo-fused tetraphenylenes 2-6 were successfully prepared by the combined deployment of the Diels-Alder cycloaddition between some strained cyclooctynes and furans and subsequent low-valent-titanium deoxygenation of the resulting 1,4-endoxides.As expecte
