Metallaphotoredox cross-coupling is a well-established strategy for generating clinically privileged aliphatic scaffolds via open-shell reactivity. The introduction of new C(sp3)-coupling partners within this paradigm can provide entry to novel, medicinally-relevant chemical space. Alkenes are abundant, bench-stable and undergo facile C(sp3)-radical reactivity metal-hydride hydrogen atom transfer (MHAT), yet metallaphotoredox methodologies invoking remain underdeveloped. Importantly, the merger MHAT activation with catalysis could enable olefins feedstock radical only activated photocatalysis, such as alcohols. Herein, we report first C(sp3)–C(sp3) coupling MHAT-activated alkenes alcohols (i.e. deoxygenative hy-droalkylation) triple co-catalysis. Through synergistic Ir Mn Ni sorting pathways, branch-selective protocol pairs diverse methanol or primary alcohols, displays remarkable functional group tolerance, enables rapid construction complex frameworks.

Unsymmetric disulfides are prevalent in natural products and essential medicinal chemistry materials science, but their robust synthesis poses significant challenges. In this paper, we report an expeditous transition-metal-free methodology for synthesizing unsymmetric through the addition of perthiyl radicals to alkenes. This study marks use generating by reacting SO2 with unactivated alkyl (pseudo)halides (Cl/Br/I/OTs). Various primary, secondary tertiary substituted different functional groups successfully function as suitable reactants. The formation involvement reaction process verified mechanistic studies DFT calculations. Overall, method leverages readily available electrophiles alkenes alongside a single setup efficiently form both carbon-sulfur sulfur-sulfur bonds simultaneously. Here, authors novel transition-metalfree

Abstract Aryl radicals are important intermediates in organic synthesis. The generation of these reactive species via direct decarboxylation inexpensive and readily available aromatic carboxylic acids is an attractive goal. However, such a process intrinsically exhibits high energy barriers to overcome, which consequence usually require precious metal catalysis, stoichiometric oxidants harsh conditions, suffering from limitations as poor functional group tolerance low atom economy. In recent years, photochemical reactions have provided new approaches address this challenge. Three major strategies been introduced emerging field: 1) one‐pot in‐situ activation benzoic generate benzoyl hypobromites or hypoiodites; 2) the use specialized photocatalysts like biphenyl/1,4‐dicyanobenzene promote through photo‐induced electron transfer charge processes; 3) LMCT (Ligand‐to‐Metal Charge Transfer) strategy where copper iron salts coordinate carboxylate anion upon visible light excitation. On basis three strategies, review will systematically summarize development visible‐light‐induced decarboxylative functionalization acids, focusing on reaction mechanism substrate scope, discuss their prospects
