All materials, including deuterochloroform (CDCl3) and aldehyde calibration standards, were purchased from Sigma-Aldrich Chemical Co. (UK), unless otherwise stated; the CDCl3 product contained the 1H NMR reference standard tetramethylsilane (TMS) at an added level of 1.00% (v/v) (equivalent to 73.45 mmol/L on consideration of its density of 0.648 g/mL). NMR tubes were purchased from Norell (Morganton, NC, USA), and EppendorfTM microcentrifuge tubes were obtained from Fisher Scientific Ltd. (Loughborough, UK).
Deuterochloroform cdcl3
Manufactured by Merck Group
Sourced in United Kingdom, United States, Germany, Macao
Deuterochloroform (CDCl3) is a common solvent used in nuclear magnetic resonance (NMR) spectroscopy. It is a deuterated form of chloroform, where the hydrogen atoms have been replaced with deuterium atoms. Deuterochloroform is used as a solvent for the analysis of organic compounds in NMR experiments due to its favorable chemical and spectroscopic properties.

1,3,5-Tris(bromomethyl)benzene, acetone, acetonitrile and deuterochloroform (CDCl3) were purchased from Sigma-Aldrich. All chemicals were of analytical grade and used directly without any further modification. 4-Oleylpyridine was prepared according to the procedure in the literature [31 (link)].
A hot plate magnetic stirrer with an aluminum heating block was used to heat the reaction. Evaporation of the solvent was accomplished with a rotary evaporator. The reaction course was routinely monitored by thin-layer chromatography on SiO2 (silica gel 60 F254), and the spots were located by either a UV light or a 1% KMnO4 solution.
NMR spectra were recorded at 400 MHz (1H) and 100.6 MHz (13C) on a Bruker Avance Neo 400 from Serveis Científics i Tecnològics de la Universitat de Barcelona (CCiT-UB); chemical shifts are reported in δ values, in parts per million (ppm) relative to Me4Si (0 ppm), or relative to residual chloroform (7.26 ppm, 77.00 ppm) as an internal standard. Data are reported in the following manner: chemical shift, multiplicity, coupling constant (J) in hertz (Hz), and integrated intensity.
High-resolution mass spectra (HMRS) were performed by CCiT-UB using an electrospray (ESI) ionization source and a TOF analyzer.

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.
