ZnCl₂ loaded TiO₂ nanomaterial: an efficient green catalyst to one-pot solvent-free synthesis of propargylamines

Abstract

A one-pot green synthesis of propargylamines using nanostructured ZnCl2–TiO2 under solvent-free conditions has been effectively accomplished. The proposed reaction protocol is sustainable, environment-friendly and offers economic viability.

Atomic Layer Deposition of Chlorine Containing Titanium–Zinc Oxide Nanofilms Using the Supercycle Approach

“…For all other samples, there is a shift towards higher energy. This shift may be due to the presence of ZnCl2 [46]. Surprisingly, the deconvolution did not show the presence of other components besides ZnO and TiO2 (Figure S3c,d).…”

Solvent-free synthesis of propargylamines: an overview

“…Later in 2019, Kanade and co-workers used nanocrystalline ZnCl 2 -TiO 2 as heterogenous catalyst for the synthesis of propargylamines from aromatic aldehydes, secondary amines and phenylacetylene (Scheme 28). 71 Excellent results were obtained when the reaction was performed using 15% ZnCl 2 loaded TiO 2 nanoparticles as the catalyst at 100 C for 6 h. Better yields and high reactivity were shown by aromatic aldehydes with halogen and electrondonating substituents. Aryl aldehydes with methoxy group at para position did not show excellent results compared to meta or ortho substituted hydroxy aldehydes.…”

Electroless Ni plated nanostructured TiO2 as a photocatalyst for solar hydrogen production

“…7f) was evinced by presence of ring like patterns that are not continuous and display regular bright spots. 77 Conrmation of such morphological features due to Ni loading was carried out by obtaining more such FETEM images as displayed in ESI Fig. S4.…”

“…For TiO 2 nanoparticles, fringes with lattice spacing of 3.50, 2.29 and 1.91 Å belonging to (101), (004), (200) planes, respectively, corresponding to the anatase phase and 3.35 and 1.70 Å with planes for (110) and (211) corroborating the presence of rutile phase were noticed. 77 The presence of nickel was ascertained by lattice spacing fringes with d -value of 1.98 Å with (111) plane. 78 The nanocrystalline nature of the samples through selected area electron diffraction (SAED) patterns ( Fig.…”
