Abstract:
Cyclobutadienes as well as the corresponding tetrahedranes were prepd. according to the Masamune route by starting from diazo compds. Low-temp. 13C-NMR measurements of the cyclobutadienes lead to the 1st exact values of the barrier heights in the interconversion of the two rectangular forms of the cyclobutadienes.
