Fluoride ion induced desilylation of cis-2-methyl-1-(substituted phenyl)-2-[(trimethylsilyl)methyl] isoindolinium iodides cis-5 gave mixtures of the Sommelet-Hauser rearrangement products 7 and the Stevens products 8 in a ratio about 8.5:1.5. Similar treatments of the trans-isomers (trans-5) afforded exclusively 8. The pathways of the ylide rearrangement are discussed.
