2,4,6-Tri(p-tolyl)pyrylium tetrafluoroborate salt (C09-1075-482)

DescriptionExcitable by blue LEDs, this photocatalyst was reported by theNicewiczlaboratory for catalysis ofO-aryl carbamothioates toS-aryl carbamothioates at ambient temperatures, an improvement from the elevated reaction temperatures traditionally needed in the Newman-Kwart rearrangment or palladium catalysis. Effective for scale-up or flow chemistry, this triarylpyrylium salt provides convenient access to thiophenols from phenols.It can also catalyze visible light-initiated, living cationic polymerization of 4-methoxystyrene with methanol under metal-free conditions.
