Carbon‐13 nuclear magnetic resonance spectra of phencyclidine analogs substituted in the piperidine and aromatic rings

Natural abundance carbon‐13 chemical shifts are reported for the hydrochloride salts of phencyclidine (1a) and twelve analogs substituted in the piperidine and aromatic rings. The signals are assigned on the basis of chemical shift theory, SFORD multiplicities, signal intensities, and comparisons with related compounds.
