Application
Excitable by blue LEDs, this photocatalyst was reported by the Nicewicz laboratory for catalysis of O-aryl carbamothioates to S-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.
