All chemicals and reagents were purchased from Sigma-Aldrich, Acros, Avera Synthesis, Spectrochem Pvt. Ltd., and used without further purification. Commercially available anhydrous solvents (THF, DMF, benzene, toluene, MeOH, EtOH, and CH2Cl2 Spectrochem) were used in the reactions. Thin-layer chromatography (TLC) was performed using precoated aluminum plates purchased from E. Merck (silica gel 60 PF254, 0.25 mm). Column chromatography was performed using Spectrochem silica gel (60–120 mesh). Melting points were determined in open capillary tubes on the Precision Digital melting point apparatus (LABCO make) containing silicone oil, and the results are uncorrected. IR spectra (neat) were recorded on an Agilent FTIR spectrophotometer. 1H and 13C NMR spectra were recorded either on an Avance III Bruker or a JEOL JNM-ECS spectrometer at operating frequencies of 200/400/500 MHz (1H) and or 100/125/150 MHz (13C) as indicated in the individual spectra using TMS as an internal standard. Elemental analyses were performed on a Carlo-Erba 108 or an Elementar Vario EL III microanalyzer. The room temperature varied between 25 °C and 30 °C. The multiplicities in the 1HNMR spectra are presented as s for singlet, d for doublet, dd for doublet of the doublet, td for a triplet of doublet, t for triplet and m for multiplet. The multiplicity in the 13C NMR spectra is presented as d for doublet.

All chemicals and solvents used
in this study were purchased from
Sigma-Aldrich and E. Merck (India). The reactions during synthesis
were monitored by thin-layer chromatography (TLC) on precoated silica
gel 60 F254 (mesh), and spots were visualized with UV light. Silica
gel (60–120 mesh) was used for column chromatography. The melting
points of all synthesized compounds were determined using the open
capillary method and may be uncorrected. The structural assignments
of the synthesized products were based on 1H, 13C NMR, MS, and single-crystal X-ray diffraction (XRD). NMR data were
collected using a 400 MHz, JEOL JNM-ECS spectrometer in CDCl3 with TMS as internal standard, and data were processed with its
Delta software. The following abbreviations were used in reporting
the spectra: s = singlet, bs = broad singlet, d = doublet, dd = doublet
of doublets, t = triplet, m = multiple. Mass data were generated using
Bruker Compass spectrometer. X-ray analysis was performed using an
Oxford Diffraction Xcalibur four-circle diffractometer with an Eos
CCD detector using graphite monochromatized Mo Kα radiation
(λ = 0.71073 Å).

All the chemicals and solvents used in the current study were purchased from E. Merck (India) and Sigma-Aldrich. The reactions during synthesis were monitored via thin layer chromatography (TLC) on precoated silica gel 60 F254 (mesh), and the spots were visualized using UV light. Silica gel (60–120 mesh) was employed for column chromatography. The melting points of all the synthesized compounds were determined using the open capillary method and may be uncorrected. The structural assignments of the synthesized products were based on 1H NMR, 13C NMR, 19F NMR, HRMS, IR and single-crystal XRD. NMR data were collected using a 400 MHz, JEOL JNM-ECS spectrometer in DMSO-d6 and CDCl3 using TMS as the internal standard and Delta software to process the data. In the reported spectral data, abbreviations such as s = singlet, bs = broad singlet, d = doublet, dd = doublet of doublets, t = triplet, and m = multiple are used. Mass data was produced with the use of a Bruker Compass spectrometer. X-ray analysis was performed using a Rigaku XtaLAB Synergy-i single crystal X-ray diffractometer with a CCD detector (HyPix-Bantam) using graphite monochromatized Cu Kα radiation (λ = 1.54184 Å).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
