THIS BRIEF NOTE is occasioned by recent observations in Germany and the Soviet Union. SchGnleber3 has remarked the thermal conversion of 1-vinylspiro[2.4]hepta-4,6-diene (l-1 to indane at 350ยฐ. In related work, Mironov, et al. 4 --reported the rearrangement of spiro[4.4]nona-1,3-diene to indane at
We wish to report the thermal behavior of the cis-bicyclo[6.2.0]decenes, I-III. 1 The known' thermal rearrangement of bicyclo[3\*2.0]hepta-2,6-diene to I II III cycloheptatriene is here shown to be extended to the bicyclic systems above which also possess the condensed cyclobutene moiety. It is also
