And the article contained the following:

Linear iodoniums are widely used as arylating reagents. However, cyclic diaryl iodoniums are ignored despite their potential to initiate dual arylations, atom and step economically. In our current work, a three-component cascade reaction of cyclic diaryliodoniums, sodium azide, and alkynes has been successfully achieved under mild conditions, catalyzed by cheap copper species. The regioselectivity associated with unsym. iodoniums was enhanced by installing two methyls ortho and para to the IIII center. The reaction enables a rapid access to a variety of complex mols., triazolophenanthridine derivatives I [R1 = H, OMe, Me, etc.; R2 = H, OMe, Me, etc.; R3 = ph, 4-Me-ph, 4-F-ph, etc.].

On December 1, 2017, Kang, Taewon; Kim, Hongsik; Lee, Dongwhan published an article.Application In Synthesis of 4-(p-Tolyl)-1H-1,2,3-triazole The title of the article was Triazoliptycenes: A Twist on Iptycene Chemistry for Regioselective Cross-Coupling To Build Nonstacking Fluorophores. And the article contained the following:

Triazoliptycene fluorophores have been designed and synthesized, in which a three-dimensional propeller-like iptycene motif is employed to suppress intermol. π-π stacking in the solid state. Key to the success of this modular synthesis is a stereoelectronic bias imposed by the iptycene scaffold, which assists the desired regioselectivity in the C-N cross-coupling step as the last-stage structure diversification from a common precursor.

Squitieri, Richard A.; Fitzpatrick, Keegan P.; Jaworski, Ashley A.; Scheidt, Karl A. published an article in 2019, the title of the article was Synthesis and Evaluation of Azolium-Based Halogen-Bond Donors.Application In Synthesis of (R)-5-Benzyl-2-mesityl-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-2-ium tetrafluoroborate And the article contains the following content:

A method for the synthesis of iodinated imidazolium and triazolium N-heterocyclic halogen-bond-donor catalysts was developed. This approach was applied to the synthesis of a variety of 1,2,4-triazolium salts to prepare a series of novel chiral halogen-bond-donor catalysts. The counterions of the iodinated triazoliums were readily exchanged with chiral and achiral non-coordinating counterions to produce unique scaffolds. Their ability to promote/catalyze a conjugate addition reaction with indole was investigated. Through these initial studies, a set of general guidelines and considerations for the application of these halogen-bond donors in organocatalysis was established. The experimental process involved the reaction of (R)-5-Benzyl-2-mesityl-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-2-ium tetrafluoroborate(cas: 1469801-67-9).Application In Synthesis of (R)-5-Benzyl-2-mesityl-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-2-ium tetrafluoroborate

On August 9, 2021, Bay, Anna V.; Fitzpatrick, Keegan P.; Gonzalez-Montiel, Gisela A.; Farah, Abdikani Omar; Cheong, Paul Ha-Yeon; Scheidt, Karl A. published an article.SDS of cas: 1469801-67-9 The title of the article was Light-Driven Carbene Catalysis for the Synthesis of Aliphatic and α-Amino Ketones. And the article contained the following:

Single-electron N-heterocyclic carbene (NHC) catalysis has gained attention recently for the synthesis of C-C bonds. Guided by d. functional theory and mechanistic analyses, authors report the light-driven synthesis of aliphatic and α-amino ketones using single-electron NHC operators. Computational and exptl. results reveal that the reactivity of the key radical intermediate is substrate-dependent and can be modulated through steric and electronic parameters of the NHC. Catalyst potential is harnessed in the visible-light driven generation of an acyl azolium radical species that underwent selective coupling with various radical partners to afford diverse ketone products. This methodol. is showcased in the direct late-stage functionalization of amino acids and pharmaceutical compounds, highlighting the utility of single-electron NHC operators. The experimental process involved the reaction of (R)-5-Benzyl-2-mesityl-6,7-dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-2-ium tetrafluoroborate(cas: 1469801-67-9).SDS of cas: 1469801-67-9
