Notes:
The rotational barriers in sulphines containing the substituents 2,6-dimethyl-3-isopropyl-4-methoxyphenyl and 4,6-dimethyl-3-isopropyl-2-methoxyphenyl are discussed. Particular attention is given to the occurrence of a barrier to rotation about the isopropyl to aryl bond. In both types of sulphines the isopropyl group is flanked by a methyl and a methoxy group. The isopropyl to aryl barrier could only be detected in the sulphines containing the second type of substituent where the o-methoxy group experiences a buttressing effect from the CSO moiety.
