Under mild condition, perfluoroalkanesulfonyl bromide also brominated phenol and anisole to give the corresponding p-bromo derivatives. Sodium α, α-dichlorotrifluoroethanesulfinate reacted with bromine in water at 25°C to form α, α-dichlorotrifluoroethanesulfonyl bromide which was thermally less...
Due to the molecular structure of alkanes and methane molecules are similar, so they have similar properties and methane: a, alkanes is stable, cant be acidic KMnO4 oxidation, does not react with strong acid, strong alkali; B. Easy to burn; C. In the light condition, it is substituted ...
The mixed anhydride is reacted with the amine of the formula (III) at a temperature between -25° C. and +5° C., preferably between 0° C. and -5° C., then the reaction is completed by stirring for additional 3 to 4 hours at room temperature. The alkanecarboxylic acid amides of...
The compound of formula XXII is then reacted in the presence of the 1:1 complex of copper(I) bromide and dimethyl sulfide with a compound of formula R2 --M (XXIII), wherein M is a metal radical, especially a halomagnesium group, to form the corresponding compound of formula XXIV ##ST...
