The reaction of phthalimidesulfenyl chloride with 2,2′,6,6′-hydroxylated biphenyls allowed the preparation of 3- and/or 3,3′-N-thiophthalimide derivatives which can be easily transformed into the corresponding thiols and/or disulfides. Mono- or bis-substitution, as well as the regiochemistry of the sulfenylation, are predictable as a function of the substituents on the biphenyl unit and the length
