A directcyanation of benzylethers and 1,3‐diarylpropenes with TMSCN was performed under solvent‐ and metal‐free conditions. This oxidative cross dehydrative coupling (CDC) reaction was promoted by 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) and provided rapid access to a broad range of nitriles in good to excellent yields.
Copper(II) catalyzed cross-dehydrogenative coupling of cyclic benzylic ethers with a variety of simple carbonyl compounds mediated by Na2S2O8 is developed. The scope of carbonyl components is broad, including simple aldehydes as well as ketones. The use of Na2S2O8 as the oxidant for the CDC reaction is attractive based on economical and environmental factors.
开发了铜(II)催化的环状苄醚与各种由Na 2 S 2 O 8介导的简单羰基化合物的交叉脱氢偶联。羰基成分的范围很广,包括简单的醛以及酮。基于经济和环境因素,使用Na 2 S 2 O 8作为CDC反应的氧化剂是有吸引力的。

A metal-free heterogeneousphotocatalytic system has been developed for highly efficient benzylic C–H oxygenations using oxygen as an oxidant. This visible light mediated oxidation reaction utilizes graphitic carbonnitride (g-C3N4) as a recyclable, nontoxic and low cost photocatalyst. Mild reaction conditions allow for the generation of synthetically and biologically valued isochromannones, phthalides
已开发出一种无金属的非均相光催化系统,用于使用氧气作为氧化剂的高效苄基CH氧化。这种可见光介导的氧化反应利用石墨碳氮化物(gC 3 N 4)作为可回收,无毒且低成本的光催化剂。温和的反应条件可从易于获得的烷基芳族前体中以高收率生成合成和生物学上有价值的异苯并二氢醌,邻苯二甲酸,异喹啉酮,异吲哚啉酮和氧杂蒽。gC 3 N 4的异质性催化系统可轻松回收和循环利用,并可多次使用而不会损失活性。通过在生物活性和具有药物价值的靶标合成中的应用,进一步证明了这种“绿色”方法的综合效用。
