Hello, I have a question. I would appreciate you helping me. I want to do a Michael addition reaction between gelatin quantum dots with NH2 terminal groups and methyl acrylate. First, I synthesized gelatin quantum dots and determined the NH2 groups by ninhydrin assay; there was 228 mmol NH2 in 1mg of quantum dot; therefore, I reacted 0.5mg of GQD with 10.3 ml methylacrylate. Second, I did the Michael reaction in a free solvent and at room temperature with a 20% molar ratio of excess methyl acrylate to complete the reaction for a day. Notably, I hypothesize that gelatin quantum dots are like aniline. Thirdly, the analysis (ATR and NMR) was matched with methyl acrylate, and I guess that the Michael addition did not happen. Would you please help me?
0.5 mol GQD miktarı yeterli olmayabilir veya çözücü miktarına azaltıp kuantum noktaları gözlemleyebilirsiniz.
