Halogenated PtIV Complexes from N‐Halosuccinimide

At the same time 2 4 equiv of succinimide is produced as the byproduct The ratio of succinimide to ethyl acetate should be 2 4:0 7 or 3 43:1 Since succinimide and ethyl acetate dissolve well in CDCl 3 we calculated the average ratio of succinimide to ethyl acetate in the reactions mentioned above on the basis of the 1 H NMR spectra

Examination of Proton NMR Spectra

Proton NMR Spectra What to Look For – 1) Number of Signals --- indicates how many different kinds of protons are present 2) Positions of the Signals --- indicates something about magnetic (electronic) environment of protons 3) Intensities (areas) of the Signals --- proportional to number of protons present 4) Splitting of a Signal Into Several Peaks --- indicates the number of nearby
