Development of high-efficiency alcohol benzoylation catalysts
Benzoylation of alcohols is an important step in organic synthesis and is widely used in the production of drugs, spices, dyes and other fine chemicals middle. This reaction usually involves the reaction of an alcohol with a benzoic acid derivative (such as benzoyl chloride or benzoic anhydride) in the presence of a catalyst to form…
Alcohol benzoylation catalyst in Friedel-Crafts acylation reaction
Friedel-Crafts acylation reaction is an important aromatic ring electrophilic substitution reaction in organic chemistry. It introduces acyl groups (RCO -) to synthesize aromatic ketones, esters and other acyl-containing compounds. The Friedel-Crafts acylation reaction usually uses a Lewis acid such as aluminum chloride (AlCl3) as a catalyst, but sometimes benzoylation of alcohols can also be used…
