Abstract
The bis[6.3.3]propellane 6 derivative of 2,2′,6,6′‐tetramethylbiphenyl was, in the final stage, synthesized by dehydration, of octaalcohol 5. X‐ray structure analysis revealed the highly symmetric shape of the molecule and disordered oxygen atoms in the tetrahydrofuran rings. The dihedral angle between LSQ phenyl planes is 62.6(1)°.

Two approaches to the synthesis of bis-3,3'-(nitro-NNO-azoxy)difurazanyl ether 2 have been tested, that is, varying the sequence of the introduction of the nitro-NNO-azoxy group and ether bridge. Difurazanyl ether formation through basepromoted transformation of nitrofurazans has been studied in whi
