In situ generated trimethylsilyl diethylphosphonoacetate from diethyl phosphonoacetic acid can be acylated with carboxylic acid chlorides in the presence of magnesium chloride to prepare a variety of β-keto phosphonates. This synthetic method is suitable for the preparation of β-keto phosphonates in the laboratory and also for large-scale production.
