WitrynaThe reagent can even undergo reaction with peroxide to form the peroxycarboxylic acid, which can react further to form diacyl peroxides. The imidazole group is also reduced by LiAlH 4 to form aldehydes from the carboxylic acid (rather than amines or alcohols). The reagent can also be reacted with Grignard reagents to form ketones. WitrynaWe discovered an unusual product during the course of an allylation reaction of silyl allylic alcohol 1 (). 12,13 When allylic alcohol was treated with sodium hydride and allyl bromide 2 in THF with heating the major product observed was not the expected allyl ether but ketone 3. 14 The mass balance of the reaction was made up of unallylated …

WitrynaSome alcohols are much more acidic; for example –OH groups attached to an aromatic ring (which are called phenols) typically have pK a ‘s around 10.
