Reductive dimerization of organic thiocyanates to disulfides mediated by tetrathiomolybdate

General and Practical Formation of Thiocyanates from Thiols

“…19 F NMR (CD3CN, 376 MHz): δ -63.6, -79. 3. The values of the NMR spectra are in accordance with reported literature data.…”

“…Following a reported procedure, 3 1-chloro-3,3-dimethyl-3-(1H)-1,2-benziodoxole 6 (23, 3.10 g, 10.5 mmol, 1.00 eq.) and silver acetate (1.83 g, 11.0 mmol, 1.05 eq.)…”

Feasible attachment of dinuclear ruthenium complex to gold electrode surface via new ligand substitution reaction

“…Tetraphenyl-phosphonium tetrathiomolybdate was obtained by the modification of literature method [18]. An aqueous solution (80 mL) of tetraphenylphosphonium chloride (4.0 g, 10 mmol) was added dropwise to an aqueous solution (300 mL) of ammonium tetrathiomolybdate (1.4 g, 5.4 mmol) under Ar atmosphere.…”

“…After substitution of the bromide group to the thiocyanate group, the resulting thiocyanates were converted to the disulfides in good yields by use of the tetrathiomolybdate. This method is a modification of recent results of reductive dimerization of organic thiocyanates to disulfides [18], which has been shown to be an effective way to produce disulfide with different type of functional groups. The newly prepared disulfides (CH 3 O 2 C-C 6 H 4 -O-(CH 2 ) n -S-) 2 were characterized by NMR and FAB-MS spectra.…”

4,4′-Azopyridine as an easily prepared and recyclable oxidant for synthesis of symmetrical disulfides from thiols or alkyl halides(tosylates)/thiourea

“…[18][19][20][21][22] According to the literature, disulfides can be obtained directly from *Corresponding author. Email: khalili@shirazu.ac.ir thiocyanates, [23][24][25] alcohols [26][27][28] and sulfonyl chlorides. [29] Alternatively, oxidative coupling of thiols represents one of the most convenient and straightforward methods for the synthesis of disulfides.…”
