Opis

Zastosowanie

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)
