Synthesis of Oligonucleotide Conjugates Employing a Diselenide Linker

Chemistry – A European Journal, EarlyView.
ABSTRACT In this study, we report the synthesis of an alkylene linker containing a terminal 2‐cyanoethyl protected selenium functionality for coupling at the 5'‐end of an oligonucleotide by solid phase synthesis for the preparation of oligonucleotide conjugates.

Germylium Catalyzed Dehydrofluorination Reactions of Fluorinated Alkanes

Chemistry – A European Journal, EarlyView.
Dehydrofluorination reactions of fluorinated alkanes catalyzed by germylium ions are reported. Computational studies of the mechanism revealed an E2 type mechanism involving a germane as a base to facilitate olefin formation in competition with an SN2 mechanism for hydrodefluorination.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Expanding Cyanide‐Bridged Weakly Coordinating Anions Through the Brominated Silver Salt Ag[BCNBBr]

Chemistry – A European Journal, EarlyView.
The brominated weakly coordinating anion [μ‐(CN)(B(C6F4Br)3)2] ([BCNBBr]−), based on two B(C6F4Br)3 units bridged by cyanide, is obtained as its silver salt Ag[BCNBBr] from CH2Cl2. Ag[BCNBBr] enables oxidation and halide abstraction reactions, affording diverse [BCNBBr]− salts with oxidizing and electrophilic cations.

Mild C─F Activation of Azido(per)Fluoroalkanes

Chemistry – A European Journal, EarlyView.
Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.
