employing a convenient modified procedure for the alkylation of NaCHI2 with alkyl iodides. Complete conversion to the diiodide is reliably obtained, avoiding a problematic separation of any remaining iodide starting material. Functional group tolerance toward olefins, acetals, ethers and silyl ethers, carbamates, and hindered esters is demonstrated. The use of an excess of LiCHI2 allows complete conversion
