  A new visible-light-promoted oxidative coupling of vinylarenes with cyclic ethers has been developed using rose bengal as photocatalyst and tert-butyl hydrogenperoxide (TBHP) as oxidant under ambient air at room temperature. A library of α-oxyalkylated ketones with broad functionalities has been synthesized in moderate to good yields. A radical mechanism is suggested for the present protocol

  A newer synthetic protocol has been developed to synthesize α-oxyalkyl ketones from vinyl azides under transition-metal-free reaction conditions. The reaction proceeds in the presence of organic photoredox catalyst rose bengal, an oxidant tert-butyl hydroperoxide (TBHP), and ethers. A broad range of substituted vinyl azides were found to react smoothly upon visible-light irradiation, which readily

  开发了一种新的合成方案，可以在无过渡金属的反应条件下从乙烯基叠氮化物合成 α-氧基烷基酮。该反应在有机光氧化还原催化剂玫瑰红（一种氧化剂叔胺）的存在下进行-丁基氢过氧化物（TBHP）和醚。人们发现多种取代的乙烯基叠氮化物在可见光照射下可以顺利反应，这很容易提供相关产品。已经进行了一些对照实验来提出可能的机制。该过程由乙烯基叠氮化物的自由基加成引发，这触发了由二氮损失驱动的级联断裂机制，稳定的醚自由基最终产生α-氧基烷基酮。该方法提供了一种简单、温和、直接、新颖的制备α-烷氧基酮的范例。

  A regioselective oxyalkylation reaction of vinylarenes with cyclic ethers was developed under the catalysis of a new heterogeneous catalyst, the diatomite-supported Mn3O4 nanoparticles (SMONP-1). The use of this heterogeneous catalyst provided a novel approach for the synthesis of alpha-carbonyled beta-alkylated aryl derivatives via a sp(3) C-H bond functionalization under mild aerobic conditions.

  A novel difunctionalization reaction of vinylarenes with cyclic ethers has been developed by copper catalysis via direct activation of alpha-sp(3) C-H bonds of oxygen in the presence of 1-1.2 equiv of TBHP under mild aerobic conditions. The reaction shows excellent regioselectivities and good functional group tolerance to give the oxyalkylated products of vinylarenes.
