Unveiling Extreme Photoreduction Potentials of Donor-Acceptor Cyanoarenes to Access Aryl Radicals from Aryl Chlorides

TL;DR: In this paper, a donor-acceptor cyanoarene-based fluorophores can undergo consecutive photoinduced electron transfer (ConPET) to achieve very high reduction potentials, which can be used to activate reductively recalcitrant aryl chlorides (Ered ≈ -1.9 to -2.79 V vs SCE).

Synthesis of Sulfoximidoyl-Containing Hypervalent Iodine(III) Reagents and Their Use in Transition-Metal-Free Sulfoximidations of Alkynes.
TL;DR: Well-defined hypervalent iodine(III) reagents incorporating transferable sulfoximidoyl groups were obtained through ligand exchange reactions of methoxy(tosyloxy)iodobenzene with NH sulf oximines in good to excellent yields, providing a new, transition-metal-free approach towards N-alkynylated sulfoxIMines.

Halocyclizations of Unsaturated Sulfoximines.
TL;DR: A method for halocyclizations of S-alkenylsulfoximines is reported, which results in S-oxides of dihydro isothiazoles and tetrahydro-1,2-thiazines in moderate to high yields with good diastereoselectivities and excellent regioselectivity.

Improving Carbene–Copper-Catalyzed Asymmetric Synthesis of α-Aminoboronic Esters Using Benzimidazole-Based Precursors
TL;DR: A one-pot protocol for efficient synthesis of α-aminoboronic esters without the need of a glovebox was developed and can be extended from aldehydes to ketones.

Photocatalytic difunctionalisations of alkenes with N-SCN sulfoximines
Duo Zhang,Han Wang,Carsten Bolm +2 more
TL;DR: 1,2-difunctionalised products are obtained, which can subsequently be derivatised taking advantage of the unique properties of the thiocyanate group.
