Elemental analyzer model 2400 chn

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.
