irradiation in the presence of catalytic amounts of [(DPEphos)(bcp)Cu]PF6 and an amine, a range of unactivated aryl and alkyl halides were shown to be smoothly activated through a rare Cu(I)/Cu(I)*/Cu(0) catalytic cycle. This complex efficiently catalyzes a series of radical processes, including reductions, cyclizations, and direct arylation of arenes.
available catalysts based on inexpensive, environmentally benign base metals are therefore strongly needed. Furthermore, expanding the toolbox of methods based on photoredox catalysis will facilitate the discovery of new light-mediated transformations. This article details the use of a simple copper complex which, upon activation with blue light, can initiate a broad range of radicalreactions.

The present invention provides 6-substituted 2,3,4,5-tetrahydro-1H-benzo[d]azepines of Formula I as selective 5-HT2C receptor agonists for the treatment of 5-HT2C associated disorders including obesity, obsessive/compulsive disorder, depression, and anxiety: I where: R6 is -C=C-R10, -O-R12, -S-R14, or -NR24R25; and other substituents are as defined in the specification.
Tin-free, photoinduced electron transfer promoted reductive radicalcyclization reactions of allyl 2-bromoaryl ethers in the presence of NaOH in 2-PrOH were found to take place efficiently to give 3-methyl-2,3-dihydrobenzofurans. In contrast to conventional radicalcyclization reactions that employ AIBN/Bu3SnH in benzene, the new method utilizes NaOH and 2-PrOH that are both readily available and benign
发现在2-PrOH中的NaOH存在下,无锡,光诱导的电子转移促进的烯丙基2-溴芳基醚的还原自由基环化反应有效地产生了3-甲基-2,3-二氢苯并呋喃。与在苯中使用AIBN / Bu 3 SnH的常规自由基环化反应相反,该新方法利用了既容易获得又良性的NaOH和2-PrOH。因此,新开发的光化学方法是进行芳基自由基环化反应的一种通用且环保的方法。
