Diphosphorus tetraiodide alkyl alcohols

New reagents for the primary and secondary alcohol to alkyl iodide conversion, with inversion at secondary centres, are diphosphorus tetraiodide (P2I4), a well characterized and stable solid, and mixtures of triphenylphosphine with iodine and imidazole or with 2,4,5-tri-iodoimidazole. The P2I4 system also iodinates tertiary alcohols. Trimethylsilyl iodide is known to convert alcohols into iodides (2,128), and some more systems that are believed to generate trimethylsilyl iodide in situ have been found to effect the alcohol to iodide conversion (c/. 3,151). Trimethylsilyl chloride-sodium iodide in acetonitrile produces iodides from alcohols direct or from their trimethylsilyl ethers. Hexamethyldisilane-... [Pg.157]
