Nah reagent with alcohol
WitrynaOne of the products on the right side is the protonated form (conjugate acid) of the alkoxide which is an alcohol. The product in this reaction is a 3 o (tertiary) alcohol which are less acidic and are at the higher end of the alcohol pKa range (16-18). An appropriate reagent for the protonation would be one with a pKa lower than 18. WitrynaShown below is a list of 16 different reagents and reaction conditions which, if selected and used in an appropriate manner, will produce the conversions shown in the diagram. Reagents & Reaction Conditions 1. Na or NaH in an ether solvent. 2. Dilute aqueous acid (H 3 O +). 3. Reaction with a 1°-alkyl halide or tosylate (R-X). 4.

We take a silyl chloride, do a substitution using the alcohol as a nucleophile and then the alcohol converted into a silyl ether can be used in the presence of any strong base including the Grignard reagent. The reaction with alcohols is carried out ...

WitrynaThe meaning of NAH is not so : no. 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.
