Diazo Transfer From Nitrous Oxide Employing Phosphorus Ylides

Angewandte Chemie, Volume 138, Issue 22, 25 May 2026.
A phosphorus ylide‐mediated strategy achieves the direct fixation of nitrous oxide (N2O) to access diazo compounds, which after intra‐ or intermolecular trapping, afford N2‐containing organic building blocks. This approach provides an alternative to hazardous diazo‐transfer reagents and establishes N2O fixation as a sustainable methodology.

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

Structure‐Based Design, Synthesis, and Biological Evaluation of Oxadiazole–Morpholine Hybrids as Potent PARP‐1 Inhibitors Inducing Apoptosis in Breast Cancer Cells

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT Poly(ADP‐ribose) polymerase‐1 (PARP‐1) plays a central role in the repair of DNA single‐strand breaks and represents an established therapeutic target in cancer treatment. In this study, a series of novel oxadiazole–morpholine hybrid compounds was designed and synthesized using a structure‐based drug design approach to target the catalytic ...

The Solid‐State Emission of AIPE‐Active Tricarbonylrhenium(I) Complexes Shifts to the Red: The Unexpected Performance of Triphenylphosphine Derivatives

Aggregate, Volume 7, Issue 7, July 2026.
New phosphino tricarbonylrhenium(I) complexes have efficient red emission in the aggregate and solid states. The good photostability and the vast possibilities of chemical modifications make these Re‐based complexes the starting point of a new generation of red emitters with aggregation‐induced phosphorescence emission (AIPE) characteristics.
