    Cu(OAc)2催化的远位苄基C(sp 3)-H氧基官能化,在无配体和无添加剂条件下,以受阻的对羟基在环境空气中作为末端氧化剂,指导C O的形成
    摘要:
    已经开发了一种受阻的对羟基定向的远程苄基C(sp 3)–H氧官能团,用于将2,6-二取代的4-甲酚,4-烷基苯酚,4-羟基苄醇和4-羟基苄基烷基醚直接转化为各种芳族羰基化合物。由乙二醇介导的无配体和无添加剂的Cu(OAc)2催化的大气氧化作用,可以使伯苄基和仲苄基官能化,形成简便,原子经济且对环境无害的C O形成。由于4-羟基苯甲醛和4-羟基苯酮的药物重要性,因此该方法对于基础研究和实际应用均具有重要价值。

    pyrolysis of lignin, including substantial amounts of 4-substituted methoxylated phenolic compounds (methoxyphenols). These compounds have been used as atmospheric markers to determine the contribution of wood smoke to ambient atmospheric fine particulate matter (PM). However, reliable quantification of methoxyphenols represents an analytical challenge because these compounds are polar, semi-volatile, and
    木材和其他生物质燃料的燃烧产生源于木质素热解的源特定有机化合物,其中包括大量的4-取代甲氧基化合物(甲氧基)。这些化合物已用作大气标志物,以确定木材烟雾对周围大气细颗粒物(PM)的贡献。但是,对甲氧基苯进行可靠的定量分析存在挑战,因为这些化合物是极性的,半挥发性的并且具有一定的反应性。我们在此报告了一种改进的气相色谱质谱法(GC / MS),用于灵敏,可靠的测定小体积环境PM样品中的甲氧基苯。在萃取之前,将代标准化合物添加到环境样品中,以确定每个样品中的分析物回收率。应用于环境PM2.5和PM10样品的分析价值分析如下:回收率= 63-100%;精度= 2-6%; 分析检出限(S / N 2)= 0.002 microg / mL;定量极限= 0.07-0.45 ng / m3(假设14 m3样品)。改进的方法应用于1999年至2000年在华盛顿州西雅图市收集的环境PM样品。观察到颗粒结合的甲氧基苯浓度在<0

    group. Under the same reaction conditions 2-methoxyphenol does not get demethylated; a mechanism to account for these findings is proposed. This reaction gives access to a variety of ortho-acylated catechols. Substituted catechols are widely used in supramolecular chemistry and are precursors of pesticides, flavors, and fragrances. Additionally, catechol moieties are found in various natural products
