Terphenylylalkanethiols with different chain length were synthesized using palladium-catalyzed cross-coupling reactions. While the thiols with two and three methylene groups were obtained via photoaddition of thiopivalic acid to the respective alkenes, the longer terphenylylalkanethiols were synthesized by two consecutive Kumada cross-coupling reactions followed by a Mitsunobu reaction for the introduction of the sulfur functionality.
