Ethyl dichloro (ethoxy) acetate (1) and methyl dichloro (methoxy) acetate (2) were characterized. The reaction of 1 and 2 with aromatics in the presence of AlCl 3 gave a considerable yield of aromatic α-keto ester. The aromatics included mono-and polymethylbenzene and anisol. The reaction was studied under various conditions and the results were compared with the acylation by ethoxalyl or methoxalyl chloride. The reaction ...
