TL;DR: This minireview aims to provide an overview of recent advancements in dearomatization of aromatic compounds, with a specific focus on visible-light-mediated dearomative transformations, and application of these transformations to the synthesis of bioactive compounds.

TL;DR: In this paper, visible light photoredox catalysis has gained attention as a versatile tool to address the challenges of the development of novel chemical transformations called for environmentally friendly synthetic methods.

TL;DR: Visible light-mediated chemical reactions have become very popular within the last 15 years as discussed by the authors, and are not anymore a merely academic field of research, finding its way increasingly into applications in the chemical and pharmaceutical industry.

TL;DR: In this article, a simple and practical synthesis of sulfonyl fluorides from sulfonamides is reported, which capitalizes on the formation of the sulfonyls chloride by virtue of the reaction of Pyry-BF4 and MgCl2, and subsequent in situ conversion to the more robust and stable S(VI) fluoride by the presence of KF.

TL;DR: In this paper, the authors proposed the CuII complex [Cu(dmp)2Cl]Cl (dmp = 2,9dimethyl−1,10phenanthroline) as an oxidation stable precursor for visible-light-mediated CuI-photoredox catalysis, being efficient and considerable more cost effective compared to previously established copper(I) photocatalysts.

TL;DR: In this article, photocatalysts can catalyze carbon-heteroatom cross-couplings by electron or energy transfer either alone or in combination with a second catalyst.

TL;DR: In this article, a manganese-catalyzed one-pot conversion of nitroarenes into Nmethylarylamines was developed, which employs a well-defined bench stable Mn PN3P pincer precatalyst in combination with methanol as both the reductant and the C1 source.

TL;DR: In this article, the authors have analyzed the ring-opening reaction of the model non-symmetrical epoxide 2,2-dimethyloxirane under basic and acidic conditions using density functional theory at OLYP/TZ2P.

TL;DR: A number of examples of this reactivity have been demonstrated recently, and strategies are emerging that allow for tuning the reagent structure in order to modulate reactivity.
