Propellanes, 10 [1] . ‐ Bis‐ and Tris(propellanes) from Methylbenzenes: 1,2;3,4;5,6‐Tris{8′,11′‐dioxa[4.3.3]propella(3′,4′)}benzene The synthesis of the title tris(propellane) 17 , derived from hexamethylbenzene, and bis(propellane) 12 is reported. Some aspects of the conformation of the compounds 12 and 17 are studied by 1 H‐NMR spectroscopy. Compound 17 exists as an equilibrium of two conformers with C 3 and C 1 symmetry. In the case of propellane 10 , the formation of an isomeric bispirane compound is discussed.
