Annulation of seven-membered rings to [2.2]paracyclophane

Tropylidenes 16 and 17 were prepared from [2.2]paracyclophane (10). On treatment with the corresponding trityl salts they were converted into tropyliophanes 26a (tetrafluoroborate) and 26b (perchlorate). With acetone, 26a furnished trapping product 27, wh

Transanular Interactions in Phanes, XXV. Structurally Isomeric Naphthalenoparacyclophanes

The structurally isomeric naphthalenoparacyclophanes 1, 2 and 3, having 1,4-, 1,5- and 2,6-bridged naphthalene moieties, respectively, were synthesized via the corresponding dithiaphanes 8, 9, 10.The photolytic desulfurization of 10 and the sulfur dioxide extrusion via vapour phase pyrolysis of the corresponding disulfone 11 to the highly strained 3 clearly demonstrate the limits of these preparative ring contraction methods.
