The 1H and 13C NMR spectra were obtained using Bruker Avance III HD-500 spectrometer. Chemical shifts were referenced to the corresponding residual solvent signal (δH 3.30/δC 49.60 for CD3OD). ESI mass spectra were obtained on an Agilent 6510 Q-TOF LC-MS spectrometer by direct injection in MeOH. HPLC was performed using a Shimadzu Instrument equipped with a differential refractometer RID-10A and YMC-ODS-A (250 × 10 mm) column. TLC was performed on Silica plates (5–17 μm, Sorbfil, Russia), and visualization was accomplished by charring at 150°C with 10% (v/v) H2SO4 in EtOH.
6510 q tof lc ms spectrometer
Manufactured by Agilent Technologies
The 6510 Q-TOF LC-MS spectrometer is a mass spectrometry instrument that combines quadrupole time-of-flight (Q-TOF) technology. It is designed to provide high-resolution and accurate mass measurements for a wide range of analytical applications.

Methylacrylate was purchased from Sigma-Aldrich and stored over 3 Å molecular sieves under an inert atmosphere. Dimethyl carbonate was purchased from Alfa-Aesar and was distilled under an inert atmosphere of argon and stored over 3Å molecular sieves.
Hoveyda-Grubbs II catalyst M72 (C627) was provided by Umicore. Column chromatography (CC) was performed with silica gel (230-400 mesh, Merck) and Sephadex LH-20 (Aldrich), while thin layer chromatography (TLC) separations were carried out on silica gel 60 PF254 (Merck). 1 H and 13 C nuclear magnetic resonance (NMR) spectra were recorded, respectively, at 400 and 100 MHz on a Bruker Avance III Ascend 400 spectrometer using CDCl3 (Sigma-Aldrich) as the solvent and using the residual signal of CHCl3 as the internal standard ( 7.26 vs TMS). Electrospray ionization -high resolution mass spectrometry (ESI-HRMS) data were measured on an Agilent 6510 Q-TOF LC/MS spectrometer, using an ESI ion source operating at positive mode. Elemental analysis was obtained in a Perkin-Elmer Elemental Analyzer model 2400 CHN. Infrared (IR) spectra were recorded with a Shimadzu FT-IR Prestige-21 instrument.

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.
