A method of direct Friedel-Crafts benzylation of arenes with benzylic alcs. using cheap and readily available bisulfate salt as the catalyst in hexafluoroisopropanol, is reported. The catalytic system is powerful with a quite diverse group of functionalized arenes and benzylic alcs. These mild conditions provide a straightforward synthesis of a variety of unsym. diarylmethanes in high yield with good to high regioselectivity. An SN1 mechanism involving activation of the hydroxy group through a hydrogen bond is proposed. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Application of 321-28-8

Panja, Subir; Ahsan, Salman; Pal, Tanay; Kolb, Simon; Ali, Wajid; Sharma, Sulekha; Das, Chandan; Grover, Jagrit; Dutta, Arnab; Werz, Daniel B.; Paul, Amit; Maiti, Debabrata published an article in 2022, the title of the article was Non-directed Pd-catalysed electrooxidative olefination of arenes.Synthetic Route of 91-16-7 And the article contains the following content:

The Fujiwara-Moritani reaction is a powerful tool for the olefination of arenes by Pd-catalyzed C-H activation. However, the need for superstoichiometric amounts of toxic chem. oxidants makes the reaction unattractive from an environmental and atom-economical view. Herein, authors report the first non-directed and regioselective olefination of simple arenes via an electrooxidative Fujiwara-Moritani reaction. The versatility of this operator-friendly approach was demonstrated by a broad substrate scope which includes arenes, heteroarenes and a variety of olefins. Electroanal. studies suggest the involvement of a Pd(II)/Pd(IV) catalytic cycle via a Pd(III) intermediate. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Synthetic Route of 91-16-7

Miyazaki, Takahiro; Kasai, Shinsei; Ogiwara, Yohei; Sakai, Norio published an article in 2016, the title of the article was Indium-Catalyzed Reductive Sulfidation of Esters by Using Thiols: An Approach to the Diverse Synthesis of Sulfides.Category: ethers-buliding-blocks And the article contains the following content:

A new reductive preparation of unsym. sulfides (i.e., thioethers) from esters and thiols in the presence of InI3 and either 1,1,3,3-tetramethyldisiloxane (TMDS) or PhSiH3 as the reductant was developed. This protocol was applied to not only benzoic acid esters that have a methoxy, Me, chloro, bromo, iodo, or trifluoromethyl group on the aromatic ring but also aliphatic acid esters with either aromatic or aliphatic thiols. A reaction mechanism is proposed by using Hammett plot results and several control experiments The synthesis of the target compounds was achieved using indium iodide (InI3) or indium bromide (InBr3) as catalysts. Starting materials included benzoic acid Me ester derivatives, benzenepropanoic acid 4-chlorophenyl ester, benzenepropanoic acid Ph ester, 1-naphthalenepropanoic acid Ph ester, benzeneacetic acid Me ester derivatives Thiol reactants included benzenethiol derivatives, benzenemethanethiol, 1-octanethiol. The title compounds thus formed included thioethers (sulfides), such as 1-methyl-4-[(phenylmethyl)thio]benzene, [2-(octylthio)ethyl]benzene, 1-methyl-4-[(3-phenylpropyl)thio]benzene. 2-[3-(Octylthio)propyl]phenol was formed from octanethiol and 3,4-dihydro-2H-1-benzopyran-2-one (i.e., hydrocoumarin).

On July 19, 2019, Chen, Yang; Qi, Hongyi; Chen, Ning; Ren, Demin; Xu, Jiaxi; Yang, Zhanhui published an article.Recommanded Product: Benzyl(4-bromophenyl)sulfane The title of the article was Fluorium-Initiated Dealkylative Cyanation of Thioethers to Thiocyanates. And the article contained the following:

Thioethers are converted to thiocyanates via fluorium-initiated dealkylative cyanation. Selectfluor is used as the oxidant, and trimethylsilyl cyanide is used as the cyanation reagent. The well-streamlined procedure is user-friendly, operationally simple, and step-economical. The current mechanistic studies show that the sulfur radical cation and cyano radical are both involved. They combine to deliver cyanosulfonium, an intermediate toward thiocyanate after dealkylation. Alternatively, a nucleophilic mechanism is also possible. This dealkylative cyanation is also efficient in synthesizing thiocyanates with strongly electrophilic functionalities. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Recommanded Product: Benzyl(4-bromophenyl)sulfane
