2,4,6-三(4-甲氧基苯基)吡啶鎓四氟硼酸盐

应用

三芳基吡喃盐在光催化和聚合中用作光敏剂。此前以货号S921874出售。2,4,6-三(4-甲氧基苯基)吡喃盐四氟硼酸盐可用于通过光致电子转移催化C2-对称环丁烷烯烃二聚体的立体选择性合成。该方法可用于柳叶玉兰脂素、endiandrin A和pellucidin A等木脂素的全合成。它还能催化光致电子转移（PET）引发自由基阳离子Diels-Alder反应。['光催化

Description

Triarylpyrylium salt used as a photosensitizer inphotocatalysisand polymerization. This was previously sold under catalog number S921874.2,4,6-Tris(4-methoxyphenyl)pyrylium tetrafluoroborate can be used to catalyze the stereoselective synthesis ofC2-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.
