All chemicals were purchased from commercial sources (Sigma Aldrich (St. Louis, MO, USA), Acros Organics (Geel, Belgium)) and used without further purification. 1H and 13C NMR spectra were recorded on a Bruker AV-300 spectrometer (Bruker Corporation, Billerica, MA, USA) (300.13 MHz and 75.46 MHz, respectively), Bruker AV-400 (Bruker Corporation, Billerica, MA, USA) (400.13 MHz and 100.61 MHz), Bruker DRX-500 (Bruker Corporation, Billerica, MA, USA) (500.13 MHz and 125.76 MHz). Mass spectra (70 eV) were recorded on a DFS Thermo Scientific high-resolution mass spectrometer. A PolAAr 3005 polarimeter (Optical Activity, Ramsey, UK) was used to measure optical rotations [α]D. Melting points were measured on a Mettler Toledo FP900 Thermosystem apparatus (Mettler Toledo, Cornellà de Llobregat, Spain). Merck silica gel (Merck, Darmstadt, Germany, 63−200 μm) (63−200 μm) was used for column chromatography. Spectral and analytical measurements were carried out at the Multi-Access Chemical Service Center of Siberian Branch of Russian Academy of Sciences (SB RAS).
Fp900 thermosystem apparatus
Manufactured by Mettler Toledo
Sourced in Spain, Switzerland
The FP900 Thermosystem is a laboratory apparatus designed for thermal analysis. It is a versatile system that can be used for a variety of applications, including differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic mechanical analysis (DMA). The FP900 Thermosystem provides precise temperature control and measurement capabilities to facilitate in-depth analysis of material properties and characteristics.

All solvents were purified by standard procedures. Chemicals were obtained from commercial sources (Merck KGaA, Darmstadt, Germany) and were used without further purification. 1 H, 13 C, and 19 F NMR spectra were recorded on Bruker spectrometers (Bruker Corporation, Billerica, Massachusetts, USA) Avance-300 (300.13, 282.37, and 75.47 MHz for 1 H, 19 F, and 13 C, respectively), Avance-400 (400.13 and 100.61 MHz for 1 H and 13 C, respectively), DRX-500 and Avance III 500 (500. 13 MHz for 1 For 19 F spectra, C 6 F 6 (δ 19 F = -162.9 ppm with respect to CFCl 3 ) was used as an external reference. 13 C NMR spectra were registered with C-H spin decoupling. Masses of molecular ions were determined by high-resolution mass spectrometry (HRMS) on a DFS Thermo Scientific instrument at an ionization energy of 70 eV (Thermo Fisher Scientific, Waltham, MA, USA) and by means of Agilent 7200 Accurate Mass Q-TOF GC/MS at an ionization energy of 70 eV (Agilent, Santa Clara, CA, USA). Melting points were registered on a Mettler-Toledo FP900 Thermosystem apparatus (Mettler-Toledo, Greifensee, Switzerland). IR spectra were recorded on a Bruker Vector-22 spectrometer for samples pelleted with KBr (0.25%). UV/Vis spectra were acquired by means of a Cary 5000 instrument (Agilent).
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.
