A pleasant and instructive reading before going to sleep 
After a long journey, finally, my good friend Sai and coworkers published this amazing work in #NatCommun. 
They can use native functional groups such as alcohols and transform them to the most challenging Z-olefins.
Without the use of a transition metal catalyst, and even working for #DNA 
functionalization!

ChemRxivC–H functionalization via single atom metathesis of C–H and C–X bondsMetathesis and reversible catalytic reactions are fundamentally intriguing and powerful tools in modern synthetic chemistry. While most reversible catalytic reactions are predicated on breaking and forming reactive functional groups, the ability to leverage the C–H bond as a functional group into metathesis reactions has proved to be exceptionally challenging. Here, we develop a C–H/C–X metathesis reaction through a radical swapping protocol where a hydrogen and halogen are traded between molecules via reversible hydrogen atom transfer (HAT) and halogen atom transfer (XAT) that allows for mild C–H halogenation. The reversibility of this process allows for selective dehalogenation of polyhalogenated products to form monohalogenated products. Leveraging the reversibility of this process, halogenated organic pollutants can also serve as a halogen source for C–H halogenation. In the broader context, this work establishes that incorporating reversible metathesis logic in C–H bond functionalization can provide complementary advantages in synthetic strategies.

#RobSelects preprint of the week #ChemRxiv: Nickel-catalyzed stereoretentive radical cross-coupling of enantiopure alkyl hydrazides with aryl halides. #catalysis https://doi.org/10.26434/chemrxiv-2025-h9snj
ChemRxivStereoretentive Radical Cross-CouplingFree radicals were first discovered over 120 years ago by Gomberg and the first radical cross-couplings demonstrated by Kochi in the 1970's. Fueled by the need for general methods to couple C(sp3)-fragments, this area has seen an explosion of renewed interest. In contrast to widely employed polar cross-coupling chemistry to forge C(sp2)–C(sp2) bonds (Suzuki, Negishi, Kumada, etc.), radical cross-coupling is advantageous when applied to the coupling of saturated systems due to the mild conditions employed and enhanced chemoselectivity associated with single electron chemistry. Indeed, the ability to employ ubiquitous carbon-based fragments (carboxylic acids, alcohols, amines, olefins, etc.) in cross-coupling has dramatically simplified access to a variety of complex molecules. Despite these advantages, enantiospecific coupling reactions involving free radicals are unknown and generally believed to be impossible due to their near-instantaneous racemization (picosecond timescale). As a result, controlling the stereochemical outcome of radical cross-coupling can only be achieved on a case-by-case basis using bespoke chiral ligands or in a diastereoselective fashion guided by nearby stereocenters. Here we show how readily accessible enantioenriched sulfonylhydrazides and low loadings of an inexpensive achiral Ni-catalyst can be enlisted to solve this vexing challenge for the first time thereby enabling enantiospecific, stereoretentive radical cross-coupling between enantioenriched alkyl fragments and (hetero)aryl halides without exogenous redox chemistry or chiral ligands. Calculations support the intermediacy of a unique Ni-bound diazene-containing transition state with C–C bond formation driven by loss of N2.

#RobSelects preprint of the week #ChemRxiv: Enantiodivergent Pd-catalyzed Stille cross-coupling controlled by the presence of a copper(I) salt. #catalysis https://doi.org/10.26434/chemrxiv-2025-mj57m
ChemRxivCu-Controlled Enantiodivergent Pd-Catalyzed Stille Cross-Coupling ReactionsWe report an enantiodivergent Pd-catalyzed cross-coupling reaction between unactivated enantioenriched alkylcarbastannatrane nucleophiles and aryl electrophiles in which the stereochemical course of the reaction is dictated by the inclusion or omission of a Cu(I) co-transmetalating agent. Use of a new electron-deficient biarylphosphine ligand (MaPhos) is required to promote the previously unreported stereoinvertive transmetalation pathway for unactivated secondary alkylstannanes. When a Cu(I) salt is included as a co-transmetalating agent, the stereochemical course of the reaction changes from stereoinvertive to
stereoretentive. Thus, both enantiomers of the cross-coupling product can be accessed in high enantiopurity using a single achiral ligand. Mechanistic investigations suggest that net-stereoretentive alkyl transfer, in the presence of Cu(I), results from consecutive stereoretentive transmetalations from tin to copper and copper to palladium. In contrast, direct alkyl transmetalation from tin to palladium proceeds primarily via a stereoinvertive pathway that is facilitated by the presence of electron-deficient ligands.
