Vibrational circular dichroism (VCD) data are presented for a series of (1R,2R)-trans-2-phenyl-1-(R-substituted)cyclopropanes where R=COOCH3, COOCD3, COOH, CONH2, COCl, CN, CH2OH, CD2OD, CH3, CD3, and NH2 (1S,2R).In addition, VCD for (1S,2S)-1-phenylpropylene oxide is presented for comparison.These data can be correlated to show certain characteristic, structure-indicating transitions common to all of the molecules.This is particularly true in the cyclopropane C-H stretching bands in the near-IR and less so of CH2 deformations and ring modes in the mid-IR.To elucidate these comparisons it is necessary to interpret the frerquency shifts of the characteristic bands as the substituent is varied.The range of compounds studied permits such an analysis for certain characteristic modes.The results for monocarbonyl and-cyano substitution further explain the presence and absence, respectively, of coupled oscillator VCD in the corresponding symmetrically disubstituted cyclopropyl compounds.
