Abstract
Pyrolysis of tricyclo[5.3.1.01,7]undeca-2,4-dien-10-one tosylhydrazone (5) in the presence of base in an aprotic solvent gave the cyclic acetylene 6 and the allene 7, while that in the presence of sodium isopropoxide in isopropanol afforded the two isopropyl ethers, 8 and 9, along with 6 and none of 7. A dynamic process of methylene flipping in the acetylenic product 6 was also revealed.
