t-BuOK-promoted methylthiolation of aryl fluorides with dimethyldisulfide under transition-metal-free and mild conditions
Huang, Dayun,Wu, Xiangmei
, (2021/03/24)
In the presence of potassium tert-butoxide (t-BuOK), the cross-coupling reaction between aryl fluorides and dimethyldisulfide was developed. A series of aryl methyl sulfides were obtained in moderate to good yields under transition-metal-free and mild conditions.

Wang, Ying-Yu,Wu, Xiang-Mei,Yang, Ming-Hua
supporting information, (2020/07/20)
An efficient route to aryl methyl sulfides through the copper-catalyzed coupling reaction of aryl iodides or bromides with dimethyl disulfide in water is described. Electron-donating and electron-withdrawing functional groups in the substrates were tolerated, and the corresponding products were obtained in moderate to good yields.

Chemical Equation Presented Creating C-F bonds: A novel electrophilic fluorination of aryl and heteroaryl Crignard reagents has been discovered and was used for the efficient synthesis of various aryl fluoride derivatives (see picture; THF = tetrahydrofuran).
Electroreduction of Organic Compounds, 19. Formation of Benzoanellated Sulfur Heterocycles by Intramolecular Cathodic Cyclization of Dithiocarboxylic Esters
Gade, Thomas,Streek, Michael,Voss, Juergen
, p. 127 - 142 (2007/10/02)
Cathodic reduction of aryl (3) and benzyl (5) dithiopivaloates and related dithioesters with leaving groups at the benzene ring or a side chain yield the sulfur heterocycles 23, 30 - 32, and 34 depending on the nature of the starting material and the reaction conditions.In the case of the α-oxo-dithioester 22, thioindigo (44) is formed. - The corresponding thioamides 14, 16, and 18 show a strong tendency to reductive dehalogenation but the S,N-heterocycles 38 and 39 are also formed in minor amounts. - The formation of the rearranged products 29 - 32, and 34 isdiscussed in terms of C,S-splitting in the primarily formed radical anion and subsequent C,C-coupling of the fragments and follow-up reactions.Key Words: Dithiopivaloates, S-aryl, S-benzyl / Electroreduction

Sindelar, Karel,Hrubantova, Marta,Svatek, Emil,Matousova, Oluse,Metysova, Jirina,et.al.
, p. 2240 - 2247 (2007/10/02)
Nucleophilic substitution reactions of a series of thio-substituted fluoroarenes with 1-methyl-4-piperidinol, 1-benzyl-4-piperidinol, and 1-methyl-4-phenyl-4-piperidinol in the presence sodium hydride in dimethylformamide gave the title compounds V-XI and XIII.The salts of these bases were pharmacologically tested and salts of compounds V, XI, and XIII showed in behavioural tests properties which are indicative of antidepressant activity.
Electroreduction of Organic Compounds, 13. - Coelectroreduction of Methyl Dithiocarboxylates with Halogenoarenes
Streek, Michael,Voss, Juergen
, p. 2251 - 2254 (2007/10/02)
Coelectroreduction of methyl dithiopivalate (1) or dithiobenzoate (11) with a monohalogenobenzene does not result in any characteristic products.However, the aryl methyl dithioacetals 7 and 8 are formed on cathodic reduction of 1 in the presence of the o-dihalogenobenzenes 4 and 5, respectively. - An SNAr mechanism is proposed, which is also in accordance with the formation of 2-bromobenzenethiolate (9) from 1 and 4 or 5.
