摘要：
An 1-Iodoalkyl acylate, which is useful as the raw material for esterification of cephalosporins, penicillins, etc. is prepared in a high degree of purity and in high yield by (1) allowing a carboxylic acid iodide to react with an aldehyde, or (2) allowing a carboxylic acid chloride to react with a salt of hydriodic acid and then allowing the resulting product to react with an aldehyde, or (3) by simultaneously allowing a carboxylic acid chloride, a salt of hydriodic acid and an aldehyde to react with one another.
