Pd‐Catalyzed C─C Bond Borylation of Biphenylenes Leading to Tri‐Ortho‐Substituted Biaryls

Chemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
Palladium‐catalyzed ring‐opening C─C borylation of 1‐substituted biphenylenes yields a range of o,o,o′‐trisubstituted biaryls with two ortho‐boryl groups via selective cleavage of the least hindered C─C bond. The resulting diborylated products are readily amenable to sequential, site‐selective postfunctionalization.

A Sustainable Borrowing Hydrogen Strategy in Natural Deep Eutectic Solvents for the N‐Alkylation of Amines From Alcohols

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
A sustainable, ligand‐free Pd‐catalyzed borrowing hydrogen protocol in a biodegradable hydrophobic natural deep eutectic solvent (NADES) (thymol/DL‐menthol) enables the N‐alkylation of primary amines with benzylic alcohols under mild, aerobic conditions, allowing efficient reuse of both catalyst and solvent for seven consecutive cycles. The hydrophobic

A Bifunctional Small Molecule Degrader of the Long Noncoding RNA MALAT1 Triplex

Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Targeting disease‐linked RNAs with small molecules is often limited by the modest impact of binding RNA structure alone. Here, we present a first‐in‐class bifunctional molecule that degrades the oncogenic lncRNA MALAT‐1 by inducing proximity between the RNA and a cleaving warhead.

Metal‐Catalyzed C(sp2)–H Bond Functionalization of Indolinone‐ and Indanone‐Type Chemical Platforms En Route Toward Late‐Stage Functionalization

Advanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
An in‐depth survey dealing with the aromatic C—H bond functionalization of biologically‐relevant scaffolds featuring the indolinone and indanone core is discussed as they are unique aromatic scaffolds that are 1,2‐doubly fused with small five‐membered rings.

Highly Active CH Bond Borylation of Aromatics With Pyridine as Convenient, Low‐Cost Ligand Under Iridium Catalysis

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
The highly atom‐economy iridium‐catalyzed CH bond borylation of aromatics has been achieved utilizing simple and trivial pyridine as the ligand, which is 2–3 orders of magnitude cheaper than the current state‐of‐the‐art ligands, thus significantly reducing both the E‐factor and the carbon footprint associated with tedious and waste‐generating ligand ...
