Rhodium-Catalyzed Generation of Anhydrous Hydrogen Iodide: An Effective Method for the Preparation of Iodoalkanes

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.

Selective C(sp3)?H and C(sp2)?H Fluorination of Alcohols Using Practical Auxiliaries

Selective introduction of fluorine into molecules by the cleavage of inert C?H bonds is of central academic and synthetic interest, yet remains challenging. Given the central role of alcohols in organic chemistry as the most ubiquitous building blocks, a

Method of preparing iodine alkane by using rhodium catalysis

The invention relates to the field of organic synthesis and discloses a synthetic method of iodine alkane. The synthetic method of the iodine alkane, disclosed by the invention, comprises the following steps: taking olefin as a starting raw material, adding a rhodium metal catalyst, a phosphine ligand, a solvent and molecular iodine into a pressurizing reaction kettle, introducing hydrogen and then synthesizing a series of the iodine alkane by using one-step reaction. The reaction temperature is 0 to 60 DEG C, the molar ratio of the rhodium metal to the olefin is (0.00001 to 1) to (0.1 to 1) and the molar ratio of the iodine to the olefin is (0.5 to 1) to (10 to 1). The synthetic method of the iodine alkane, disclosed by the invention, has obvious advantages of wide application range, short process flow and low cost of the raw materials; the synthetic method of the iodine alkane is suitable for industrialized production of a series of the iodine alkanes.

Copper-Catalyzed Alkylation of Aliphatic Amines Induced by Visible Light

Although the alkylation of an amine by an alkyl halide serves as a textbook example of a nucleophilic substitution reaction, the selective mono-alkylation of aliphatic amines by unactivated, hindered halides persists as a largely unsolved challenge in organic synthesis. We report herein that primary aliphatic amines can be cleanly mono-alkylated by unactivated secondary alkyl iodides in the presence of visible light and a copper catalyst. The method operates under mild conditions (-10 °C), displays good functional-group compatibility, and employs commercially available catalyst components. A trapping experiment with TEMPO is consistent with C-N bond formation via an alkyl radical in an out-of-cage process.

Method for the Preparation of Iodoalkanes

The present invention relates to an atom economic procedure of preparing iodoalkanes by hydroiodination of alkenes. In particular the present method features the generation of anhydrous hydrogen iodide from atomic hydrogen and iodine in situ by using transition metal precursor and phosphine ligandcatalyst.
