애플리케이션

2,4,6-Tris(4-methoxyphenyl)pyrylium tetrafluoroborate can be used to catalyze the stereoselective synthesis of C2-symmetric cyclobutane alkene dimers via photo-induced electron transfer. This method can be employed for the total synthesis of lignans such as magnosalin, endiandrin A and pellucidin A. It can also catalyze photoinduced electron transfer (PET) to initiate radical-cation Diels-Alder reactions.
Triarylpyrylium salt used as a photosensitizer in photocatalysis and polymerization. This was previously sold under catalog number S921874.

Product can be used with our line of photoreactors: Including Penn PhD (Z744035) & SynLED 2.0 (Z744080)

Electron transfer catalysis is an effective method for the acceleration of Diels-Alder reactions between two substrates of similar electron density. The dependence of the selectivity of the Diels-Alder reaction between (R)-alpha-phellandrene and 4-methoxystyrene catalyzed by photoinduced electron transfer with tris(4-methoxyphenyl)

The Nicewicz lab is focused on the discovery of new and powerful reaction methodologies that proceed via the intermediacy of highly reactive cation radical species. Included in these transformations are anti-Markovnikov selective additions of amines, alcohols, carboxylic acids, amides and mineral acids to alkenes.
