It is a mild reagent, suitable for both acid and base sensitive compounds. Its great … Skatīt vairāk Fétizon's reagent is typically prepared by adding silver nitrate to an aqueous solution of a carbonate, such as sodium carbonate or potassium bicarbonate, while being vigorously stirred in the presence of purified celite. Skatīt vairāk Fétizon's reagent is used primarily in the oxidation of primary or secondary alcohols to aldehydes or ketones with a slight selectivity toward secondary alcohols and unsaturated alcohols. The reaction is typically done in a refluxing dry non-polar organic solvent … Skatīt vairāk While tertiary alcohols are typically not affected by Fétizon's reagent, tertiary propargylic alcohols have been shown to oxidize under these conditions and results in the fragmentation of the alcohol with an alkyne leaving group. Halohydrins that … Skatīt vairāk A proposed mechanism for the oxidation of an alcohol by Fétizon's reagent involves single electron oxidation of both the alcoholic oxygen … Skatīt vairāk Para-methoxybenzyl (PMB) is a commonly used protecting group for alcohols against Fétizon's reagent.
