Mercury 300

The ¹H NMR spectra were recorded in CDCl₃, CD₃OD or D₂O on the following spectrometers: Varian Mercury-300 and Bruker Avance III (600 MHz) with TMS as an internal standard; chemical shifts δ in ppm with respect to TMS; coupling constants J in Hz. The ¹³C NMR spectra were recorded for CDCl₃, CD₃OD or D₂O solutions on Varian Mercury-300 and Bruker Avance III (600 MHz) machines at 75.5 and 150.5 MHz, respectively. The ³¹P NMR spectra were recorded in CDCl₃, CD₃OD or D₂O on Varian Mercury-300 and Bruker Avance III (600 MHz) spectrometers at 121.5 and 243 MHz, respectively.
IR spectra were measured on an Infinity MI-60 FT-IR spectrometer. Melting points were determined on the Boetius apparatus. Elemental analyses were performed by the microanalytical laboratory of the host institution on Perkin Elmer PE 2400 CHNS analyzer and the results were found to be in good agreement (±0.3 %) with the calculated values.
The following absorbents were used: column chromatography, Merck silica gel 60 (70–230 mesh); analytical TLC, Merck TLC plastic sheets, silica gel 60 F₂₅₄. TLC plates were developed in chloroform–methanol solvent systems. Visualization of spots was effected with iodine vapours. All solvents were dried according to standard literature methods.

IR spectral data were measured on an Infinity MI-60 FT-IR spectrometer. Melting points were determined on a Boetius apparatus and are uncorrected. Elemental analyses were performed by the Microanalytical Laboratory of this Faculty on a Perkin Elmer PE 2400 CHNS analyzer. Polarimetric measurements were conducted on an Optical Activity PolAAr 3001 apparatus.
The following adsorbents were used: column chromatography, Merck silica gel 60 (70–230 mesh); analytical TLC, Merck TLC plastic sheets silica gel 60 F₂₅₄. TLC plates were developed in chloroformmethanol solvent systems. Visualization of the spots was effected with iodine vapours. All solvents were purified by methods described in the literature.
All microwave irradiation experiments were carried out in a microwave reactor Plazmartonika RM 800. The reaction carried out in 50 mL-glass vials.
