Some Experiments to Generate all ‐ cis ‐1,2,3‐Triformylcyclopropane and all ‐ cis ‐1,2,3,4‐Tetraformylcyclobutane Ozonolysis of bullvalene ( 3 ) and the dimer 6 of COT followed by reduction should generate all ‐ cis ‐1,2,3‐triformylcyclopropane ( 4 ) and all ‐ cis ‐1,2,3,4‐tetraformylcyclobutane ( 7 ). We have been unable to isolate 4 and 7. 4 escapes via an intermolecular “polymerisation” and 7 cyclizes intramolecularly giving the tetracyclic acetal 2b of all ‐ cis ‐1,2,3,4‐tetraformylcyclobutane.
