: Palladium-catalyzed cross-coupling reactions have gained a continuously growing interest of synthetic organic chemists. The present review gives a brief account of applications of the palladium-catalyzed cross-coupling reactions in comprehensive synthesis, viz., the Heck, Stille, Suzuki–Miyaura, Negishi, Sonogashira, Buchwald–Hartwig, Ullmann and the Oxidative, decarboxylative cross-coupling reactions, with particular emphasis on the synthesis of heterocyclic compounds.

This review article provides a detailed overview of the synthesis techniques of biomass-based graphene aerogels and highlights the influence of fabrication parameters on the performance of the resulting aerogels for wastewater treatment applications.

N-doped graphene nanosheets synthesised from biomass are used as a PL probe for the on-off-on detection of Pb ²⁺ and guanine.
