Why is it better to acquire the 1H-NMR spectrum in DMSO-d6 and not in CDCl3? In the experiment, potassium permanganate is used to oxidize 2-chlorotoluene (o-chlorotoluene)to 2-chlorobenzoic acid (o-chlorobenzoic acid). Permanganate solutions are less hazardous thanthose containing chromium compounds, which are often carcinogenic.CH3СООН1. КMnO4, H,0, д2. HCІ, Н-ОClClThe yield of the reaction observed in the literature (Clarke, H. T.; Taylor, E. R. Org. Synth. 1930,10, 20) is 76-78 % before recrystallization and 65-67 % after recrystallization.
