Below is the HNMR spectrum for dimedone in deuterated DMSO. I need to find the equilibrium constant for the enol/ketone equilibrium. Not sure how to do this since I dont see a prominent signal for the ketone methylene protons? Also the enol should be more prominent in this solvent because of its polarity, but there is no significant OH peak. I am really confused, would appreciate any help. Thanks. 7.69 5.15 2.25 10 12 6 2 2 PPM Nolumes/Lexar/Dimedone/HNMR dimedone...
