β¦ Synopsis
I3C chemical shift data are reported for a series of para-substituted I-methyl-I-phenylcyclohexanes at 22 and -100 OC. The magnitudes of the SCS at alkyl and cycloalkyl carbon positions are discussed. The SCS at C-methyl and C-4 are significantly different in the two chair conformations. The variation at C-methyl is appraised in terms of the orientation of the aromatic ring.
