摘要：

Nucleophilic demethylation of trimethyl (1) and dimethyl 2-pyridylmethyl (2) phosphates by iodide is catalysed by alkali metal ions, the eff ect increasing in the order K+ < Na+ < Li+ and being more pronounced for 2; crown ethers reduce, but do not eliminate the catalysis, indicating strong interactions between the reaction transition state and the metal ions.
