Phosphinoisocyanide/Alkyne Cycloaddition: Generation of Azaphospholylidene (NPHC) Ligands
Angewandte Chemie, EarlyView.Rare examples of nitrogen phosphorus heterocyclic carbene (NPHC) complexes of group 6 and 7 metals arise from a facile [3 + 2] cycloaddition of phosphinoisocyanides (LnM‐CNPR2) with activated alkynes. The NPHC ligands are shown to be comparatively π‐acidic and the group 6 examples undergo facile transfer of the intact carbene to gold(I) centres ...

Catalytic degradation of diverse azo dyes using Eucommia ulmoides bark-mediated gold nanocatalyst
Environmental Chemistry and EcotoxicologyIn the absence of any hazardous substances, colloidal gold nanoparticles (AuNPs) were synthesized through the reduction and stabilization of corresponding metal cations by a simple Eucommia ulmoides bark extract (EUBE). Employing these AuNPs as catalysts,

Facile N═N Bond Cleavage of Cis‐Azobenzene with Bis‐silylenes
Angewandte Chemie, EarlyView.The unexpectedly easy N═N bond scission of cis‐azobenzene using two bis‐silylenes with different spacers and distinct SiII···SiII distances is reported. While both bis‐silylenes enable C─H and N═N π‐bond activation of trans‐azobenzene, the cooperative disilicon(II)‐mediated activation of cis‐azobenzene leads to bis‐silamines (Si═N) and related novel ...

Enaminone‐Based Push–Pull Chromophores: Synthesis, Optical Properties, and Computational Insights
Asian Journal of Organic Chemistry, EarlyView.Enaminones, known for their pharmacophoric properties, were combined with alkyne units to create complex chromophore structures through click‐type [2 + 2] cycloaddition‐retroelectrocyclization reactions. The ICT characteristics of the synthesized compounds were analyzed using both experimental and computational approaches.
