Abstract Recently CO2 stabilization has received a great deal of attention because of its probable applications as a rich C1 resource and the synthesis of several fine chemicals can be accomplished through this stabilization. In this study, Sn(IV) doping dendritic fibrous nanosilica (SnD) supported P rVO4 nanoparticles as a catalyst ( PrVO4/SnD) was synthesized by a in-situ procedure. The SnD with the ratios of Si/Sn in a variety of 6 to 40 were acquired through direct hydrothermal synthesis (DHS), and PrVO4 NPs on the surfaces of SnD were reduced in-situ. X-Ray diffraction (XRD), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and X-ray energy dispersive spectroscopy (EDS) were deployed for identifying the P rVO4/SnD. It is potentially a highly dynamic catalyst in the stabilization of CO2 for the production of 2-oxazolidinones and benzimidazoles. In addition, the catalyst is very easy to recycle and reuse without significant loss of active site Cu metal.

1 Introduction It is now accepted that many natural compounds [1–3] and drugs on the market [4–9] have at least one heterocyclic material in their anatomy [10–20]. Amongst the heterocyclic material, the five-membered cyclic carbamates, i.e. 2-oxazolidinones, is a significant category of compounds that are present in numerous medicines (e.g. beflooxatone, toloxatone, cimoxatone, zolmitriptan, etc.) [21–24], divers anti-bacterial agents (e.g., Linezolid, Toloxatone, Tedizolid), and agrochemicals (e.g. phosalone) [25]. Moreover, they act

against multiply resistant Gram-positive pathogens [26, 27]. These products were employed in asymmetric synthesis as chiral auxiliaries [28] and effective intermediates in different organic compound production reactions [29]. In general, 2-oxazolidinones are produced from carbon monoxide with 2-amino alcohols [30
