The existence of toblerone implies the existence of related triangular hydrochocolate chains such as the base alkane (toblerane), as well as the closed ring form (cyclotoblerone)
@azonenberg Split off the side chain to yield tobleral, reduce the carboxyl of that to yield toblerol, or oxidise the hydrogen to yield tobleroic acid, react two equivalents of toblerol under dehydrating conditions to form ditobleryl ether...
@zuthal @azonenberg I think there are some chemists lurking in these chat rooms...
