note
-
Tetra-tert-butylcyclooctatetraene 6 was obtained in the laboratory of Professor G. Maier by photolysis of 3,4-di-tert-butylcyclobutene-1,2-dicarboxylic acid anhydride; Fritschi, G., Ph.D. Thesis, 1971, Karlsruhe, Germany. Photolysis of the above anhydride produced five hydrocarbons of similar polarity containing 6 (in about 2% yield), in addition to two ketones. It was suggested that 1,4,5,8-tetra-tert-butylcyclooctatetraene ( 6a ) is sterically a more stable isomer than 1,2,5,6-tert-butylcyclooctatetraene ( 6c ).
