Triphenylamine (98%), phosphorus(v ) oxychloride (99%), sodium borohydride (96%), sodium acetate (99%), triethylamine (anhydrous, 99.5%), acryloyl chloride, sodium acetate, 2,2′-azobis(2-methylpropionitrile) (AIBN, 98%), 4-methoxyTriphenylamine (97%), iron(iii ) chloride (97%), N,N-dimethylformamide (DMF, 99.8%), methyl alcohol (99.8%), 1-methyl-2-pyrrolidinone (NMP, 99%) and anhydrous chloroform (99%) were all purchased from Sigma Aldrich and used as received. Tetrahydrofuran (Boom) and toluene (Macron) were dried using the MBraun SPS800 system. Carboxylic-acid functionalized multiwall carbon nanotube (MWCNT-COOH, 9.5 nm × 1.5 micron) was also purchased from Aldrich and used with no further treatment.
Sps800 system
Manufactured by MBraun
The SPS800 system is a laboratory equipment designed for solvent purification and drying. It provides a controlled environment for the removal of water and other impurities from solvents, ensuring the purity of the final product. The system operates based on established principles of solvent purification and drying, utilizing various components and techniques to achieve the desired level of solvent quality.

All reactions were carried out
under a nitrogen atmosphere using standard Schlenck techniques. Compound
[Mo3S4H3(dmpe)3]Cl was
prepared by following literature procedures.28 (link) The remaining reactants were obtained from commercial sources and
used as received. Solvents were purified by using a MBRAUN SPS-800
system. 1H, 13C{1H}, and 31P{1H} NMR spectra were recorded on a Bruker Avance III HD 400
MHz using CD2Cl2 as a solvent and referenced
to the residual protons of the deuterated solvent or to 85% H3PO4. ESI-mass spectra were recorded using a Premier
Q-TOF (quadrupole-hexapole-TOF) mass spectrometer with an orthogonal
Z-spray electrospray source (Waters, Manchester, UK). Time-of-flight
(TOF) mass spectra were acquired in the V-mode at a resolution of
ca. 10 000 [full width at half-maximum (fwhm)]. Chemical identification
of the cluster species was carried out by comparing the experimental
and theoretical isotopic patern calculated from their elemental composition
by using the MassLynx 4.1 program.36 The
kinetics of reaction of the cluster with FA was studied using a Cary
50 Bio spectrophotometer provided with a thermostated multicell accessory.
All of the experiments were carried out under pseudo-first-order conditions
of acid excess. The reaction was monitored by following the spectral
changes at a wide spectral range, and the data were analyzed using
the program Specfit.37

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.
