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).

GENERATION OF CYCLOPROPYLIDENES FROM GEM-DIHALOPROPANES UNDER ULTRASONIC IRRADIATION

Cyclopropylidenes can be generated much quickly by reactions of gem-dihalocyclopropanes and metals (Li, Na or Mg) under ultrasonic irradiation.The reactions usually complete in 5-15 min at room temperature.
