Cyclopropyl-substituted sulfonium salts are obtained by Rh-catalysed addition of α-diazo dibenzothiophenium to olefins. When indenes used as substrates, initially formed cyclopropyl rings open with concomitant elimination dibenzothiophene, enabling access 2-substituted naphthalenes.

Herein, we present the discovery and development of first photoredox-catalyzed alkoxy diazomethylation alkenes with hypervalent iodine reagents alcohols. This multicomponent process represents a new disconnection approach to diazo compounds is featured by broad scope, mild reaction conditions, excellent selectivity. Key was generation diazomethyl radicals, which engaged alcohols in an inter- intramolecular fashion oxidative radical–polar crossover leading unexplored β-alkoxydiazo compounds. The synthetic utility such demonstrated series transformations involving C–H, N–H, O–H insertions as well construction complex sp3-rich heterocycles.

Fluorine and nitrogen form a successful partnership in organic synthesis, medicinal chemistry, material sciences. Although fluorine-nitrogen chemistry has long rich history, this field received increasing interest made remarkable progress over the past two decades, driven by recent advancements transition metal organocatalysis photochemistry. This review, emphasizing contributions from 2015 to 2023, aims update state of art synthesis applications nitrogen-based organofluorine functional molecules chemistry. In dedicated sections, we first focus on fluorine-containing reagents organized according type groups attached nitrogen, including N-F, N-RF, N-SRF, N-ORF. review also covers nitrogen-linked building blocks, catalysts, pharmaceuticals, agrochemicals, underlining these components' broad applicability growing importance modern

The photoactivation of electron donor-acceptor complexes is a useful tool for the generation radical species in synthetic chemistry. However, alkene difunctionalization via catalytic remains less developed. Herein, we report versatile an complex platform alkenes without need precious transition metal catalysts or synthetically elaborate organic dyes. By taking advantage visible light potential aggregates between triarylamines and S-fluoromethyldiaryl sulfonium salts, photoinduced single-electron transfer initiated to generate stable cation, which acts as endogenous oxidant convert addition intermediate into cationic species. Subsequent N-nucleophilic enables styrenes. This general photocatalyst-free protocol applied fluoroalkylative sulfonamidation, amidation, hydrazidation, azidation, anilination reactions under mild conditions.
