Explanation:
The reaction shown here is the reaction between an acyl chloride and a carboxylic acid. This reaction produces an acid anhydride.
The first step in the reaction is the nucleophillic attack of the acid on the acyl carbon of the acyl chloride. This is followed by loss of HCl to yield the acid anhydride as shown in the image attached.
The product formed is PhCOOCOCH3.
