| ¹H NMR reaction monitoring (300 mg Beads–SH, 1.5 mL of 50 mM methyl acrylate in deuterated acetonitrile, room temperature, benzyl alcohol internal standard) | The acrylate vinyl signals at approximately 5.8 – 6.5 ppm and the methyl ester signal near 3.8 ppm decreased gradually, with the peaks becoming nearly undetectable after 12 h |
