A photoredox-assisted reductiveacyl cross-coupling reaction of two different carboxylic acid esters was developed for ketone synthesis. The reaction proceeded smoothly under mild conditions using Hantzsch ester (HE) as an organic reductant, with high chemoselectivity and functional group compatibility. A large range of aryl and 1°, 2°, 3°-acyl electrophiles, and 1°, 2°, 3°-alkyl radical precursors

Synthesis of symmetrical and unsymmetrical naphth-annelated thienyl heterocycles has been achieved via thionation of hydroxyketones/diketones using Lawesson's reagent. Photophysical studies of 1,3-disubstituted naphtho[c]thiopheneanalogs are presented. Electro-oxidative behavior of these naphtha-annelated thiophenes are investigated using cyclic voltammeter.
通过使用Lawesson试剂对羟基酮/二酮进行硫磺化,已经完成了对称和不对称的萘环化噻吩基杂环的合成。提出了1,3-二取代萘[ c ]噻吩类似物的光物理研究。使用循环伏安法研究了这些石脑油-退火噻吩的电氧化行为。

Photocatalytic oxidation is a popular transformation way for organic synthesis and is widely applied in academia and industry. Herein, we report a blue light-induced alkylation–oxidation tandemreaction for the synthesis of diverse ketones by combining alkyl radical addition and oxidation of alkenyl borates. This reaction shows excellent functional group compatibility in acceptable yields, and diversity
