Abstract
4-Hydroxycoumarin and dimedone, two carbonyl compounds, which are known to form enoles readily, are treated with trimethylchlorosilane in the presence of triethylamine to give their hitherto unknown trimethylsilyl derivatives.
A solvent-dependent, reversible migration of the trimethylsilyl group was observed by means of1H-NMR-spectroscopy.
