3,3'-Bicyclopropenyl (1) was synthesized from a new isomer 3 of 1 -chloro-2-(2-chloro-3-trimethylsilyicycloprop-1 -yl)-3-trimethylsilylcyclopropanes, which was formed by ene dimerization of 1-chloro-3-trimethylsilylcyclopropene (2) foUowed by reduction with diimide.

## Abstract The enantiomers of 3,3,3′,3′‐tetramethyl‐1,1′‐spirobi[3 __H__,2,1]benzoxaselenole have been separated on a chiral preparative chromatographic column. The experimental vibrational circular dichroism (VCD) spectra have been obtained for both enantiomers in CH~2~Cl~2~. The theoretical VCD
