some Grignard reagents with β-keto phosphonates results in nucleophilic addition to the carbonyl group to afford β-hydroxy phosphonates with extension of the carbon skeleton. Additions of allylmagnesium reagents have proven particularly efficient, especially in the presence of BF3·OEt2. Reactions of allylic zinc reagents with β-keto phosphonates also gave the desired β-hydroxy phosphonates, often in even

Nucleophilic addition to the carbonyl group of β-keto phosphonates has been studied with several Grignard reagents. Allyl magnesium halides have proven particularly effective.
