TL;DR: The first example of a practical and direct trifluoromethylthiolation reaction of unactivated aliphatic CH bonds employs a silver-based reagent and is operationally simple, scalable, and proceeds under aqueous conditions in air.
Abstract: The first example of a practical and direct trifluoromethylthiolation reaction of unactivated aliphatic CH bonds employs a silver-based reagent. The reaction is operationally simple, scalable, and proceeds under aqueous conditions in air. Furthermore, its broad scope and good functional-group compatibility were demonstrated by applying this method to the selective trifluoromethylthiolation of natural products and natural-product derivatives.

TL;DR: In this article, an environmental, economic and highly effective method for carbon fiber hydroxylated-functionalization based on Fenton's reagent treatment is used to improve the electrochemical activity of graphite felt (GF) as the positive electrode in all vanadium redox flow battery (VRFB).

TL;DR: In this article, a chiral titanium catalyst generated in situ from dichlorodiisopropoxytitanium and a tartrate-derived chiral diol was used for cycloaddition.
Abstract: In the presence of certain Lewis acids, alkenes containing an alkylthio group (for example, ketene dithioacetals, alkenyl sulfides, alkynyl sulfides, and allenyl sulfades) react with electron defficient olefins to give the corresponding cyclobutene, or methylene cyclobutane derivatives. By employing a chiral titanium catalyst generated in situ from dichlorodiisopropoxytitanium and a tartrate-derived chiral diol, the [2+2] cycloaddition reaction proceeds with high enantioselectivity

TL;DR: A Sandmeyer-type difluoromethylation process has been developed that allows the straightforward conversion of (hetero-)arenediazonium salts into the corresponding diffluorometHyl (heterO-)arenes under mild conditions.
