A Study of Alkene Disulfonoxylation [PDF]
Medicinal Chemistry ResearchWe have developed convenient protocols for alkene disulfonoxylation, which involve stirring alkene substrate with a commercial I(III) oxidant and sulfonic acid in CH2Cl2 at ambient temperature. The reactions can be performed open to air without any special precautions to exclude moisture and, in most cases, deliver the products of vicinal ...

Catalytic, contra-Thermodynamic Alkene Isomerization [PDF]
, 2021 The positional isomerization of C–C double bonds is a powerful strategy for the interconversion of alkene regioisomers. However, existing methods provide access to thermodynamically more stable isomers from less stable starting materials.

A general alkene aminoarylation enabled by N-centered radical reactivity of sulfinamides [PDF]
, 2022 We disclose an intermolecular 1,2-aminoarylation of alkenes using aryl sulfinamide reagents as bifunctional amine and arene donors. This reaction features excellent regio- and diastereoselectivity on a variety of activated and unactivated substrates ...

Alkene-oxo and alkene-alkene coupling on Pt(II) [PDF]
, 2021 Tetranuclear Pt(II) oxo-complex [(COD)4Pt4([mu]3-O)2Cl2](BF4)2 (1) (COD = 1,5- cyclooctadiene) was found to readily react with a variety of alkenes (ethylene, norbornene, propylene and cyclopentene). The most significant discovery resulted from the norbornene reaction, which gave platinaoxetane [(COD)2Pt2(OC7H10)Cl]BF4 (4), the first metallaoxetane ...

Iodoaminations of Alkenes [PDF]
Synthesis, 2016 The activation of alkenes and their subsequent functionalization is a frequently used methodology in synthetic chemistry. This review highlights recent iodine-mediated aminations and elaborates on the various strategies to bring about regio- or stereoselective transformations.

Temperature-Regulated Regiodivergent Synthesis via Alkene Migratory Hydroalkylation [PDF]
, 2022 An approach for reliable and predictable carbon-carbon or carbon-heteroatom bond formation that produces either regioisomer starting from the same raw materials, also known as a regiodivergent methodology, is highly desirable.

Alkene Dialkylation via Triple Radical Sorting [PDF]
, 2023 The development of bimolecular homolytic substitution (SH2) catalysis has expanded cross-coupling logic by enabling the selective merger of any primary radical with any secondary or tertiary radical via a radical sorting mechanism.
