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, EarlyView.
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.

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Glycerol carbonate formation from glycerol and dimethyl carbonate using lithium‐based catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Excess glycerol from biodiesel production can be sustainably converted into value‐added products like glycerol carbonate, for its use in polymers, solvents, and as ecofriendly alternative as green chemical in various chemical industries. This study aims to synthesize a catalyst optimized for the glycerol and dimethyl carbonate (DMC) conversion
