ChemInform Abstract
Desilylative elimination reactions of the oxiranes (I), (III), and ( VII) generates intermediate allene oxides (cf. (V)). They are trapped by a halide or excess alkoxide to yield the corresponding α- substituted ketones. The method presented is a significant improvement for the generation of the title compounds and their trapping by alcohols.
