a palladium
Conformation of unsymmetrical diaryl disulfides1. In solution the unsymmetrical p-substituted diaryl disulfides have
a skewed conformation with
a Polarizations, polarizabilities, and conformations of the aryl methyl disulfides1. Each of the aryl methyl disulfides exists in skew conformation with
a C-S-S-C dihedral angle
