Theoretical and synthetic studies of the tricyclic 10π-electron hydrocarbon cyclobuta[1,2:3,4]-dicyclopentene (1), a nominally aromatic structure that has never been synthesized, are described. Geometry optimization by density-functional-theory calculatio
Stereoselective formation of cyclic bisallenes from 5,5,10,10-tetrabromotricyclo[7.1.0.0.4,6] decanes

The stereochemical outcome of the title conversions is predicted and tested. Within detection limits, the transformations of the stereoisomeric compounds1,2,3, and5 to the cyclic bisallenes 9 and 10 occur stereospecifically.1 -3 all yieldmeso compound9;5 givesrac-10. Isomer4 is not yet available for analogous experiments. (Chemical Equation Presented).
