WebMay 20, 2024 · 1) Since the − O H of the phenol is quite acidic, it undergoes rapid H X + / D X + exchange with the D X 2 O. My expectation is that the − O H signal from the original phenol will get reduced and broadened (maybe even disappear, but I am not sure) because it is replaced with an − O D group.
