phosphonylcarbenes is dramatically reduced as one changes the neighbouringgroup from the phosphonate ester to the acid anion, and phosphonatecarbenes are experimentally classified as typical nucleophiles; the results are nicely explained in terms of neighbouringphosphonategroupparticipation in which the vacant p orbital strongly interacts with the phosphonate oxygen anion resulting in suppression of the availability
