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).
