Abstract
This paper reports the halocyclization of alkynoic thioesters, as S-nucleophiles, with N-halosuccinimide, followed by oxidative aromatization with the same reagent for the one-pot synthesis of thiophenes, important heterocycles exhibiting remarkable applications in different disciplines. Brief mechanistic studies were also performed to elucidate the halocyclization process. The potential diverse applications of the product, dihydrothiophene, were also assessed.

Abstract
In organic synthesis, due to their high electrophilicity and leaving group properties, halogens play pivotal roles in the activation and structural derivations of organic compounds. Recently, cyclizations induced by halogen groups that allow the production of diverse targets and the structural reorganization of organic molecules have attracted significant attention from synthetic chemists. Electrophilic halogen atoms activate unsaturated and saturated hydrocarbon moieties by generating halonium intermediates, followed by the attack of carbon-containing, nitrogen-containing, oxygen-containing, and sulfur-containing nucleophiles to give highly functionalized carbocycles and heterocycles. New transformations of halogenated organic molecules that can control the formation and stereoselectivity of the products, according to the difference in the size and number of halogen atoms, have recently been discovered. These unique cyclizations may possibly be used as efficient synthetic strategies with future advances. In this review, innovative reactions controlled by halogen groups are discussed as a new concept in the field of organic synthesis.

Abstract
A Pd-catalyzed Sonogashira cross-coupling reaction for the synthesis of C4-alkynylisoxazoles from 3,5-disubsitituted-4-iodoisoxazoles and terminal alkynes was described, which could afford the corresponding products with high yield (up to 98%). The results indicated that the steric effect from the group at the C3 position of the isoxazole had greater influence on the cross-coupling reaction than that from the group at the C5 position. In addition, the group at the C3 position of the isoxazole showed negligible electronic effects on the cross-coupling reaction. Furthermore, a gram-scale reaction of the Sonogashira coupling reaction was also investigated. Finally, a plausible mechanism for the Sonogashira coupling reaction was proposed. A Pd-catalyzed Sonogashira cross-coupling reaction for the synthesis of C4-alkynylisoxazoles from 3,5-disubsitituted-4-iodoisoxazoles and terminal alkynes was described, which could afford the corresponding products with high yield (up to 98%).![]()

Abstract
Iodocyclization of silyl group-substituted homopropargylic carbamates and amides proceeded via 6-exo-dig mode to afford 6-vinylene-4,5-dihydro-1,3-oxazines in moderate to quantitative yields. This is the first report for silyl group-solely directed iodocyclization of alkynes utilizing the β-silyl effect. Under these mild reaction conditions, various functionalities such as secondary alcohol, acetal, urea, and sulfide were tolerated.

Abstract
A new fluorosulfonylation reagent 1-bromoethene-1-sulfonyl fluoride was developed (1-Br-ESF). This unique reagent possesses three addressable handles (vinyl, bromide, and sulfonyl fluoride) and has great potential to function as a tris-electrophile and as a sulfur(vi) fluoride exchange (SuFEx) clickable material to enrich the SuFEx tool cabinet. The application of this reagent for regioselective synthesis of 5-sulfonylfluoro isoxazoles has been realized through a [3+2] cycloaddition with N-hydroxybenzimidoyl chlorides. This practical protocol provides a general and direct route to functionalized isoxazoles possessing sulfonyl fluoride moieties.

Abstract
A facile approach for the synthesis of substituted iodo-benzo[a]phenazines from 2-aryl-3-(aryl/alkylethynyl)quinoxalines via 6-endo-dig ring closure has been described under mild reaction conditions. Iodocyclization proceeds through the iodonium ion intermediate followed by nucleophilic cyclization with the C-H bond of the arene. Furthermore, the resulting 6-iodo-5-aryl/alkyl benzo[a]phenazine derivatives allowed for structural diversification by employing various coupling reactions. The structure of iodo-benzo[a]phenazine was confirmed by X-ray crystallographic studies of the compound.

Abstract
A versatile approach to isoxazolines and pyrazolines by the cyclization of alkyne substrates using tetrabutylammonium fluoride (TBAF) is described. The reported diheteroatom cycles were produced under mild reaction conditions and with broad product scope. Evidence is also provided for a vinyl anion intermediate produced under unusually mild conditions, which was trapped in situ as part of a tandem cyclization/aldehyde addition sequence. Finally, a deprotection/functionalization method is described, leading to a substituted pyrazoline in good diastereoselectivity.

Abstract
A tandem synthesis for structurally novel 3-chloro-4-iodoisoxazoles was developed by simply mixing 1-copper(I) alkynes, dichloroformaldoxime, and molecular iodine together. The combination of 1-copper(I) alkyne and molecular iodine was well used as a synthetic equivalent of 1-iodoalkyne without the need for tedious preparation, purification, and storage of 1-iodoalkyne.

Abstract
An iodocyclization reaction of o-alkynylphenyl carboxaldehydes is reported that is truly catalytic with respect to the electrophilic iodine source. With a combination of tetrabutylammonium iodide (TBAI), Oxone as non-nucleophilic and easy to handle co-oxidant, and fluorinated protic solvents, highly substituted 1-naphthalenones could be prepared in high yields of up to 91%.

Abstract
We have developed a new method of iodocyclization based on reagent-controlled oxidative aromatization. Our strategy takes advantage of the dual nature of iodine as both an iodinating and an oxidizing agent. This approach enabled "product switch" and enhanced the flexibility of the synthetic pathway toward pyrazoles and isoxazoles. In addition, the iodo moiety of the cyclized product could create further diversity. The utility of our methodology was demonstrated in the synthesis of valdecoxib and its 2,5-dihydro analogs.
