Phenylthio migrations in rearrangements of 2,2-bisphenylthioethanols
Abstract
Thionyl chloride causes rearrangement of the title compounds to give 2,3-bisphenylthiopropenes (12) by a [1,2] phenylthio shift. The products undergo [1,3] phenylthio shifts on exposure to light. Some applications to synthesis are described.
