Abstract

General.'H and 13C NMR spectra were recorded on 200-and 400-W spectrometers (CDC1, solvent, TMS internal standard). The multiplicities of the 13C spectra were determined by the attached proton test (ATP), which produced positive (+) quaternary C and CH2 signals and negative (-) CH and CH3 signals. IR spectra were recorded on an FTIR spectrophotometer in CCl, solution using NaCl solution cells. Mass spectra were obtained using electron- ...
