Small rings, 36. Attempts to Synthesize Tetramethyltetrahedrane from Alicyclic Precursors

Synthesis as well as the thermal and photochemical behaviour of compounds with ring skeletons 1 and 3 are described.Whereas the former are accessible by standard procedures the approach to the bicyclobutane derivatives is based on the isomerization of diester 1b into valence isomer 3b which can be achieved in good yield by SiO2 or Al2O3.There are only minor differences in the cleavage of the pairs 1/3 provoked by heating or photochemical excitation.This is even true for irradiations in argon at 10 K.Under those conditions anhydrides 1a and 3a form the samecharge transfer complex 28a between tetramethylcyclobutadiene and phthalic anhydride.A direct detection of tetramethyltetrahedrane using these means is not possible.
