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). The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Category: ethers-buliding-blocks

An efficient electrochem. method for benzylic C(sp3)-H bond oxidation has been developed. A variety of methylarenes, e.g., p-chlorotoluene, methylheteroarenes, e.g., 6-methylquinoline and benzylic (hetero)methylenes, e.g., p-ethyltoluene could be converted into the desired aryl aldehydes, e.g., 4-chlorobenzaldehyde/e.g., quinoline-6-carbaldehyde and aryl ketones, e.g., 1-(p-tolyl)ethan-1-one in moderate to excellent yields in an undivided cell, using O2 as the oxygen source and lutidinium perchlorate as an electrolyte. On the basis of cyclic voltammetry studies, 18O labeling experiments, and radical trapping experiments, a possible single-electron transfer mechanism has been proposed for the electrooxidation reaction.

On August 31, 2021, Bao, Can-Can; Luo, Yan-Long; Du, Hui-Zhen; Guan, Bing-Tao published an article.SDS of cas: 578-58-5 The title of the article was Benzylic aroylation of toluenes with unactivated tertiary benzamides promoted by directed ortho-lithiation. And the article contained the following:

The deprotonative functionalization of toluenes, for their weak acidity, generally needed strong bases, thus led to the requirement of harsh conditions and the generation of byproducts. Direct nucleophilic acyl substitution reaction of amides with organometallic reagents could provide an ideal solution for ketone synthesis. However, the inert amides and highly reactive organometallic reagents brought great challenges for an efficient and selective synthetic approach. Herein, an lithium diisopropylamide (LDA)-promoted benzylic aroylation of toluenes with unactivated tertiary benzamides, providing a direct and efficient synthesis of various aryl benzyl ketones ArC(O)CH2Ar1 [Ar = Ph, 3,4-di-MeOC6H3, 2-naphthyl, etc.; Ar1 = Ph, 4-MeOC6H4, 3,5-di-MeC6H3, etc.] was reported. This process featured a kinetic deprotonative functionalization of toluenes with a readily available base LDA. Mechanism studies revealed that the directed ortho-lithiation of the tertiary benzamide with LDA promoted the benzylic kinetic deprotonation of toluene and triggered the nucleophilic acyl substitution reaction with the amide. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).SDS of cas: 578-58-5

On January 7, 2022, Gu, Yuanyun; Zhang, Zhen; Wang, Yan-En; Dai, Ziteng; Yuan, Yaqi; Xiong, Dan; Li, Jie; Walsh, Patrick J.; Mao, Jianyou published an article.Formula: C8H10O The title of the article was Benzylic Aroylation of Toluenes Mediated by a LiN(SiMe3)2/Cs+ System. And the article contained the following:

Chemoselective deprotonative functionalization of benzylic C-H bonds is challenging, because the arene ring contains multiple aromatic C(sp2)-H bonds, which can be competitively deprotonated and lead to selectivity issues. Recently it was found that bimetallic [MN(SiMe3)2 M = Li, Na]/Cs+ combinations exhibit excellent benzylic selectivity. Herein, is reported the first deprotonative addition of toluenes to Weinreb amides mediated by LiN(SiMe3)2/CsF for the synthesis of a diverse array of 2-arylacetophenones. Surprisingly, simple Me benzoates also react with toluenes under similar conditions to form 2-arylacetophenones without double addition to give tertiary alc. products. This finding greatly increases the practicality and impact of this chem. Some challenging substrates with respect to benzylic deprotonations, such as fluoro and methoxy substituted toluenes, are selectively transformed to 2-aryl acetophenones. The value of benzylic deprotonation of 3-fluorotoluene is demonstrated by the synthesis of a key intermediate in the preparation of Polmacoxib. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Formula: C8H10O
