• General Description: Titanium (IV) iodide (TiI4), also known as tetraiodotitanium or titanium tetraiodide, is a reagent demonstrated to facilitate the hydroiodination of alkenes and alkynes, yielding alkyl iodides, vinyl iodides, and alkyl diiodides efficiently. It exhibits versatility in promoting C–C bond formation, particularly in the presence of acetals, leading to products such as 1,3-diiodides from olefins and 1,5-diiodo-1,4-dienes from alkynes under mild conditions (e.g., CH2Cl2, room temperature). While its mechanistic role remains under investigation, TiI4 proves effective in synthetic transformations, offering good yields and broad substrate compatibility.

An intriguing hydroiodination of alkenes and alkynes with titanium tetraiodide

10.1055/s-2005-872679

The research discusses a novel hydroiodination reaction of alkenes and alkynes using titanium tetraiodide (TiI4) as a reagent, which results in the formation of alkyl iodides, vinyl iodides, and alkyl diiodides with good yields. The study explores the reaction conditions and substrate scope, revealing that the presence of acetals leads to intriguing C–C bond-forming products, such as 1,3-diiodides from olefins and 1,5-diiodo-1,4-dienes from acetylenes. The experiments involve treating various olefins and alkynes with TiI4 in CH2Cl2 at room temperature, with optimization of reaction conditions to achieve the best yields. The analyses used to characterize the products include purification by silica gel TLC and spectral methods, with the yields of products reported in a table format. The research also touches upon the potential intermediates and mechanisms involved in the reaction, although these are not yet fully confirmed.
