All synthetic procedures were performed under nitrogen either in a Vacuum Atmospheres glovebox or in a closed reactor. Acetophenone, 4-toluenesulfonyl chloride, 4-fluorobenzenesulfonyl chloride, 2-picolylamine, [Cp*IrCl2]2, potassium tert-butoxide, formic acid (97%), and NaHCO3 were purchased from common vendors and used without further purification. NMR solvents (CD2Cl2, CDCl3, and C6D6), 2-propanol, and triethylamine were dried and distilled over CaH2. Hexane and CH2Cl2 were dried using a solvent purification system.
1H, 13C, and 19F NMR spectra were acquired on Varian Mercury 400, VNMRS-500, and VNMRS-600 spectrometers and processed using MestReNova 12.0.1. All chemical shifts are reported in ppm and referenced to the residual 1H or 13C solvent peaks. Following abbreviations are used: (s) singlet, (bs s) broad singlet, (d) doublet, (t) triplet, (dd) doublet of doublets, etc. NMR spectra of all metal complexes were taken in 8” J. Young tubes (Wilmad or Norell) with Teflon valve plugs. MALDI-MS spectra were acquired on Bruker Autoflex Speed MALDI Mass Spectrometer. X-ray crystallography data were obtained on a Bruker APEX DUO single-crystal diffractometer equipped with an APEX2 CCD detector, Mo fine-focus and Cu micro-focus X-ray sources. IR spectra were obtained using Jasco FT/IR-4600 FT-IR Spectrometer.

Globar light
micro FT-IR spectroscopy was performed using an IRT-7100 IR microscope
with the FT/IR-4600 FT-IR spectrometer (JASCO) equipped with a high
brilliant ceramic light source, liquid nitrogen-cooled single mid-band
MCT detector, and 32× Cassegrain objective (NA = 0.75). FT-IR
spectra were recorded in transmission mode as the average of 256 scans
from 600 to 4000 cm–1 at a spectral resolution of
4 cm–1, with an aperture size of 10 × 10 μm2. The measurement points were scanned at 2.5 × 2.5 and
10 × 10 μm2, and the spectra were converted
to text data files using Spectra Manager version 2 (JASCO).

All of the materials for synthesis were purchased from commercial suppliers and used without further purification. The absorption spectra were recorded on a Shimadzu UV-PC-2401 UV-vis spectrophotometer using 10 mm path length quartz cuvettes in the range 300−800 nm wavelengths, while the fluorescence measurements were carried on a Horiba Jobin-Yvon FluoroMax-4 spectrofluorometer using 10 mm path length quartz cuvettes with a slit width of 5 nm at 298 K. FT–IR spectra were measured on a JASCO FTIR 4600 FT–IR spectrometer with 4 cm−1 resolution and 32 scanned between wave number 4000 cm−1 and 400 cm−1. Samples were prepared KBr disks with 1 mg of complex in 100 mg of KBr. The mass spectra of RH using Agilent Technologies 6520 Accurate mass spectrometer. NMR spectra were recorded on a Varian FT-400 MHz instrument. The chemical shifts were recorded in parts per million (ppm) on the scale. The following abbreviations are used to describe spin multiplicities in 1H NMR spectra: s = singlet; d = doublet; t = triplet; m = multiplet.

Cellulose nanofibers were purchased from Sigma Aldrich. Iron(iii) chloride, iron(ii) sulfate, cobalt(ii) acetate, and sodium hydroxide were purchased from Sigma Aldrich. All chemicals were used without further purification. The FT-IR spectra were recorded on a JASCO FT/IR 4600 FT-IR spectrometer. The thermal analysis (TGA) was carried out using a TGA Q600 TA instrument at a heating rate of 10 °C min−1 in air. The powder X-ray diffraction (XRD) was performed with a Philips PW1730. The scanning electron microscopy (FESEM) and the energy dispersive X-ray spectroscopy (EDS) characterization of catalysts was performed using an electron microscope Tescan MIRA3. The melting points of the products were measured by an electrothermal 9100 apparatus. ICP experiments were accomplished using a Varian Vista Pro CCD simultaneous ICP-OES instrument. Magnetic properties of the nanoparticles were measured with a vibrating sample magnetometer (VSM). Transmission electron microscopy (TEM) was performed on a Philips EM208 microscope and was operated at 100 kV.

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.
