Abstract
A Mn(II)-catalyzed Markovnikov hydroiodination of terminal aryl alkynes with TMSI as the iodination reagent has been developed. Cheap Mn(OAc)2·4H2O was employed as the catalyst. Twenty-five aryl alkynes (including two internal alkynes) were successfully transformed into their α-iodide styrene derivatives, including those natural product-based alkynes and poly alkynyl benzenes. The reaction has good chemoselectivity of alkynes over alkenes, which enabled the tolerance of olefin in the substrate. Gram-scale synthesis was also conducted.

Abstract
Presented herein is a facile stereoselective construction of synthetically versatile chiral and achiral (E)-α-haloenamides under mild conditions utilizing N-halosuccinimides and diphenylphosphine oxide. This reaction is metal-free, mild, efficient, very rapid, and practical and highlights the synthetic versatility of ynamides. The reaction has a broad substrate scope; both chiral and achiral ynamides have been transformed into the corresponding (E)-α-haloenamides within a very short period of time without compromising selectivity or complexity.

Abstract
A rhodium-catalyzed anti-Markovnikov hydroiodination of aromatic and aliphatic terminal alkynes is reported. Depending on the choice of ligand and substrate, either (E)- or (Z)-configured alkenyl iodides are obtained in high to exclusive isomeric purity. The reaction exhibits a broad substrate scope and high functional group tolerance, employing easily accessible or commercially available aliphatic iodides as HI surrogates through a shuttle process. The synthesized vinyl iodides were applied in several C-C and C-heteroatom bond-forming reactions with full retention of the stereoselectivity. The developed method could be used to significantly shorten the total synthesis of a marine cis-fatty acid. Additionally, initial deuterium-labeling experiments and stoichiometric reactions shed some light on the potential reaction mechanism.

Abstract
Herein, we report an efficient and practical hydroiodination of internal alkynes using HI generated ex situ from the readily available triethylsilane and I2. This system offers high regio- and stereoselectivity to afford (E)-vinyl iodides in good yields under mild conditions. Furthermore, the hydroiodination reaction shows high functional group tolerance toward alkyl, methoxy, halogen, trifluoromethyl, cyano, ester, halomethyl, acid-sensitive silyl ether, and acetal moieties.

Abstract
Iodine is an element that exhibits characteristic features of heavy halogen, and
several compounds containing iodine constitute important synthetic intermediates due to
synthetically easy manipulation. To utilize iodine units for organic synthesis, a highly regio-
and stereoselective introduction of iodine to versatile building blocks is significant,
and a lot of research works for the selective introduction of iodine to alkynes or alkenes
have been conducted. In this review article, we describe regio- and stereoselective hydroiodination
to multiple bonds of building blocks, and its synthetic applications as key
intermediates to construct several important compounds in organic chemistry.

Abstract
The design and a gram-scale synthesis of a bench-stable cyclohexa-1,4-diene-based surrogate of gaseous hydrogen iodide are described. By initiation with a moderately strong Brønsted acid, hydrogen iodide is transferred from the surrogate onto C-C multiple bonds such as alkynes and allenes without the involvement of free hydrogen iodide. The surrogate fragments into toluene and ethylene, easy-to-remove volatile waste. This hydroiodination reaction avoids precarious handling of hydrogen iodide or hydroiodic acid. By this, a broad range of previously unknown or difficult-to-prepare vinyl iodides can be accessed in stereocontrolled fashion.

Abstract
The use of liquid sulfur dioxide as a reaction solvent to promote chemical transformations of alkynes has been explored. First, a combination of liquid SO2 and In(OTf)3 or Hf(OTf)4 as a catalyst allows to perform hydration of aryl alkynes under mild conditions without a direct addition of Brønsted acid. Second, novel catalyst-free conditions for the synthesis of α-vinyl iodides, bromides, and chlorides from aryl alkynes have been developed in liquid SO2 using group I and II metal halides and ammonium iodide as the halide ion sources.
