Electrocatalytic Nitrate Reduction to Hydroxylamine: Breaking the Activity‐Selectivity Trade‐Off by Designer Bifunctional Metal‐Organic Frameworks

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
A bifunctional metal‐organic framework (MOF) catalyst with dual active sites is developed for enabling NH2OH electrosynthesis via NitRR with both high selectivity and activity. ABSTRACT Electrocatalytic nitrate reduction reaction (NitRR) offers a promising route for hydroxylamine (NH2OH) synthesis under ambient conditions.

Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, Volume 32, Issue 11, 16 March 2026.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Diselenide‐Catalyzed Asymmetric Allenylation of Alkynes

European Journal of Organic Chemistry, Volume 29, Issue 11, 16 March 2026.
An asymmetric allenylation of alkynes is described using chiral lactamides‐based diselenides under oxidative conditions. This led to the corresponding allenylamides with enantiomeric excesses up to 72%, and uncovers an interesting stereodivergency feature related to the β‐H‐syn‐elimination of transient Se(IV) intermediates.
