How to Make a Phosphine by Catalytic Hydrophosphination

Chemistry–Methods, Volume 6, Issue 9, September 2026.
Catalysis is the winning hand for hydrophosphination. Three general advances, electrophilic metals, ionic and solvent effects, and photocatalysis have allowed for large categories of unsaturated and phosphine substrates to be accessed. Through these advances, a catalyst that can provide good conversion for most substrates can now be found. Implications

A Physical Organic Odyssey: From the Ultrafast Dynamics of Carbenes and Nitrenes to Contemporary Chemical Biology and Drug Discovery

Journal of Physical Organic Chemistry, Volume 39, Issue 9, September 2026.
Physical organic chemistry transforms photoaffinity labeling from empirical photochemistry into rational probe design. By measuring reactive‐intermediate lifetimes, pathways, and selectivity, Platz's legacy connects carbene and nitrene mechanisms to modern chemoproteomics, enabling more precise protein labeling and drug‐discovery maps.

Solvent‐Responsive Porous Organic Cage‐Based Membranes With Switchable Pore Openings for Molecular Sieving and Heavy Metal Recovery

Small, Volume 22, Issue 52, 16 September 2026.
An in situ fabricated porous organic cage membranes (PCM) exhibits reversible solvent pore switching property in response to water and methanol. Water stimulated structural rearrangement enables selective removal of Rh B and heavy metal ions (Ni2+ and Zn2+), whereas methanol stimulates the pore expansion promotes Ni2+ and Zn2+ ions recovery.
