The preparation of anhydrous hydrogen iodide directly from molecular hydrogen and iodine using a rhodium catalyst is reported for the first time. The anhydrous hydrogen iodide generated was proven to be highly active in the transformations of alkenes, phenyl aldehydes, alcohols, and cyclic ethers to the corresponding iodoalkanes. Therefore, the present methodology not only has provided convenient access to anhydrous hydrogen iodide but also offers a practical preparation method for various iodoalkanes in excellent atom economy.
首次报道了使用铑催化剂直接从氢气和碘制备无水碘化氢。生成的无水碘化氢被证明在烯烃、苯甲醛、醇和环醚向相应的碘代烷烃的转化中具有高度活性。因此，本方法不仅提供了方便获得无水碘化氢的途径，而且还为各种碘代烷烃提供了一种在极好的原子经济性下的实用制备方法。
