TL;DR: Zinc is the 24th most abundant element in the Earth's crust and has been widely used as a catalysts in the last three decades as mentioned in this paper ; however, the main application of zinc metal is as materials.
Abstract: Zinc is the 24th most abundant element in the Earth’s crust. Since the discovery of pure zinc metal in the 18th century, the main application of zinc metal is as materials. Because zinc salts are abundant, cheap, non-toxic, and exhibit environmentally benign properties, organic chemists have been interested in using zinc salts as catalysts in organic synthesis during the last three decades. Within this review, we have summarized the progress on applications of zinc salts in organic reactions. Our the target is to emphasize the special properties of zinc catalysts, and further promote the interest of organic chemists.

TL;DR: In this paper, the reusability of the nano particle as a catalyst in the synthesis of coumarins is described, and the zinc oxide (ZnO) nanoparticles function as highly effective catalyst for the reactions of various o-hydroxy benzaldehydes with 1,3-dicarbonyl compounds.
Abstract: Green chemistry protocols with the reusability of the nano particle as catalyst in the synthesis of coumarins is described. The zinc oxide (ZnO) nanoparticles functions as highly effective catalyst for the reactions of various o-hydroxy benzaldehydes with 1,3-dicarbonyl compounds under microwave and thermal conditions to afford the corresponding coumarins in moderate to good yields. The catalyst is inexpensive, stable, can be easily recycled and reused for several cycles with consistent activity.

TL;DR: ZnO nanopowder has been successfully synthesized by a microwave-assisted solution approach using Zn(CH 3 CO 2 ) 2 ·2H 2 O and NaOH.
Abstract: ZnO nanopowder has been successfully synthesized by a microwave-assisted solution approach using Zn(CH 3 CO 2 ) 2 ·2H 2 O and NaOH. The results obtained from X-ray diffraction (XRD), scanning electron microscopy (SEM) and transition electron microscope (TEM) show that the mean particle size is 30 nm. SEM and TEM micrographs of ZnO nanopowder also reveal that nanoparticles have spherical shape. Catalytic activity of ZnO nanopowder for O -acylation of alcohol and phenol has been investigated. The results show that the reaction time by using ZnO nanopowder has been reduced by almost 24 times with higher yield than ZnO bulk.
