The traditional method for the synthesis of biaryl's uses organometallic reagents for the arylation reactions. There are certain drawbacks associated with such traditional methods. Use of expensive metals, metal impurities in the products formed and disposal of metal waste generated are major problems that need to be taken care of. Thus, research has been focussed on using transition metal free catalyst for cross coupling reactions to encourage green environment and it still remains a challenge for researchers. Carbonaceous catalyst have attracted great attention recently as a heterogeneous catalyst as it has a carbon skeleton that is stable, easily separable, reusable, eco-friendly and highly economical compared to other heterogeneous catalyst. Carbonaceous catalysts have been studied in variety of organic reactions such as hydrolysis, dehydration, esterification, alkylation, condensation, oxathioketalization, dimerization, benzylation and trimethylsilylation, etc. It was estimated that - stacking interactions between carbonaceous catalyst and arenes will accelerate the coupling reaction. However to the best of our knowledge, there are no reports available in literature on use of carbonaceous catalyst for direct arylation of arenes. And thus, we developed a new method for C-H arylation of unactivated arenes with aryl halides using a transition metal free D-glucose derived carbonaceous catalyst.&lt;/p&gt;

	Direct oxidative C-3 ketoalkylation of quinoxalin-2(1H)-ones with cyclopropanols using ammonium persulfate in an aqueous medium has been achieved in a moderate to good yield. The reaction does not require metals, light-source, or catalysts to facilitate the reaction and could be efficiently utilized to construct a wide range of biologically relevant 3-ketoalkylated quinoxalin-2(1H)-ones.&lt;/p&gt;

	Herein, we report a catalyst-free and mild synthetic method for the construction of hindered N-alkyl sulfoximines derivative. A wide range of hindered di-alkyl sulfoximines can be readily obtained from the reaction of alpha-bromo-hydroxamates with a variety of sulfoximines, including diaryl, aryl-alkyl, di-alkyl and heteroaryl sulfoximines.&lt;/p&gt;

	The development of synthetic routes for the formation of robust porous organic polymers (POPs) with well-defined nanoscale morphology is fundamentally significant for their practical applications. The thermodynamic characteristics that arise from reversible covalent bonding impart intrinsic chemical instability in the polymers, thereby impeding their overall potential. Herein, a unique strategy is reported to overcome the stability issue by designing robust imidazole-linked POPs via tandem reversible/irreversible bond formation. Incorporating inherent rigidity into the secondary building units leads to robust microporous polymeric nanostructures with hollow-spherical morphologies. An in-depth analysis by extensive solid-state NMR (1D and 2D) study on H-1, C-13, and N-14 nuclei elucidates the bonding and reveals the high purity of the newly designed imidazole-based POPs. The nitrogen-rich polymeric nanostructures are further used as metal-free electrocatalysts for water splitting. In particular, the rigid POPs show excellent catalytic activity toward the oxygen evolution reaction (OER) with long-term durability. Among them, the most efficient OER electrocatalyst (TAT-TFBE) requires 314 mV of overpotential to drive 10 mA cm(-2) current density, demonstrating its superiority over state-of-the-art catalysts (RuO2 and IrO2).&lt;/p&gt;
