	abstract = {Composites comprising of metallic nanoparticles in polymer matrices have allured significant importance due to multifunctionalities. Here a simple protocol has been described to embed Ni nanoparticles in carboxymethyl guar gum (CMGG) polymer. The composite formation helps in the stabilization of Ni nanoparticles which are otherwise prone towards aerial oxidation. Further the nanoparticles retain their superparamagnetic nature and catalytic capacity. Ni-Polymer composite catalyses the reduction of 4-Nitrophenol to 4-Aminophenol very efficiently in presence of NaBH4, attaining a complete conversion under some experimental conditions. Ni-Polymer composite is well characterized using UV{\textendash}vis spectroscopy, FTIR, XPS, powder XRD, TGA, SEM and TEM. A detailed magnetic measurement using superconducting quantum interference device-vibrating sample magnetometer (SQUID-VSM) reveals superparamagnetic behaviour of the composite.},

	The hydroamination reaction, defined as the direct addition of an N-H bond across unsaturated carbon-carbon bonds, provides a direct route to substituted amines. These amines are indispensable building blocks in nitrogen-containing heterocycles, which are central to pharmaceuticals, agrochemicals, and fine chemicals. Unlike conventional multistep processes, hydroamination enables streamlined and sustainable access to diverse organo-nitrogen frameworks. Within this context, zinc-catalyzed intra- and intermolecular hydroaminations have emerged as particularly attractive due to zinc{\textquoteright}s abundance, low toxicity, wide availability, and its ability to enable efficient catalytic processes with reduced environmental impact. Zinc catalysts operate under mild, environmentally benign conditions, displaying broad substrate compatibility and potential for enantioselective control through coordination with chiral ligands. This review highlights the progress made in zinc-catalyzed hydroamination, encompassing homogeneous and heterogeneous systems, structure-activity relationships, mechanistic insights, and emerging applications. Particular attention is given to the advantages of zinc catalysis in organic synthesis and its relevance to industrial-scale transformations.</p>
