We have reinvestigated the report that dimesitylsilylene adds nonstereospecifically to cis- and trans-2-butene. Stereospecific addition of dimesitylsylene to cis- and trans-2-pentenes and -4-octenes produced the corresponding siliranes. A photoisomerization pathway is also reported for these siliranes. A probable explanation for the earlier and spurious interpretation is given
