Starting materials
2-chloro-4-methylphenol, 2-fluoro-4-methylphenol (Chem Scene), 2-bromo-4-methylphenol,
titanium(IV) isopropoxide (Aldrich), 2,4-dimethylphenol (Fluka), N,N-diethylethylenediamine (Alfa Aesar),
formaldehyde 37% (J.T. Baker), and methanol (Bio-lab) were used as
received. Tetrahydrofuran (Bio-lab) was dried by solvent purifiers
MB-SPS. Elemental analysis of C, H, and N was performed on a Thermo
Flash 2000 CHN-O elemental analyzer; Elemental analysis of Cl, Br,
and F was performed by Anton Paar Microwave Induced Oxygen Combustion
(MIC) for the decomposition of organic samples by Dionex LC20 ion
chromatography. High-resolution mass spectrometry was conducted using
a Q Exactive Plus mass spectrometer (Thermo Fisher Scientific) coupled
with a Dionex UltiMate 3000 UPLC system (Thermo Fisher Scientific).
Solutions for ¹H and ¹³C NMR spectra were prepared
in DMSO-d₆ or THF-d₈ (Cambridge Isotope Laboratories, INC), measured at 400 and
125 MHz, respectively, and analyzed with TopSpin 4.0.6, Bruker Corporation.
The chemical shifts were referenced to Me₄Si (δ 0.00
ppm) and DMSO-d₆ (δ 2.5 ppm) or
THF d₈ (δ 3.58 and 1.72 ppm). Hydrolysis
studies were performed by ¹H NMR spectroscopy at 298 K
with 32 scans using 1,4-dinitrobenzene (Sigma Aldrich) as the internal
standard, recording the spectra at 500 MHz.

All manipulations except ligand synthesis were performed inside an N₂-filled Innovative Technologies glovebox. Tetrahydrofuran (THF), benzene, toluene, and n-hexane were purchased from Sigma-Aldrich, dried under Ar using a solvent purification system (Innovative Technologies), transferred to the glovebox, and stored over activated 3A molecular sieves. Benzene-d₆, toluene-d₈, and THF-d₈ (Cambridge Isotope Laboratories) were distilled over CaH₂ or with Na/benzophenone and then degassed and stored over 3 A molecular sieves. ¹H Nuclear Magnetic Resonance (¹H NMR) spectra were recorded on a 500 MHz Varian Inova spectrometer or a 300 MHz Mercury spectrometer equipped with a three-channel 5 mm indirect detection probe with z-axis gradients. Chemical shifts were reported in δ (ppm) and were referenced to solvent resonances: δH = 7.26 ppm (CDCl₃), 7.16 ppm (C₆D₆), 2.09 ppm (C₇D₈), and 3.58 ppm (C₄D₈O). Fourier Transform Infrared (FT-IR) spectra were recorded as solids on a Thermo Fisher iS5 instrument equipped with an ATR diamond crystal stage using OMNIC software package. 2,4,6-heptatrione was synthesized following the literature procedure.²⁹

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.
