Mild electrophilic trifluoromethylation of carbon- and sulfur-centered nucleophiles by a hypervalent iodine(III)-CF3 reagent
Kieltsch, Iris,Eisenberger, Patrick,Togni, Antonio
, p. 754 - 757 (2007)
Inexpensive, recyclable, and activable: these are the features of a new mild electrophilic trifluoromethylation reagent that can be used to transfer a CF3 group to C-centered nucleophiles, such as β-keto esters and α-nitro esters, and to S-centered nucleophiles (see scheme). (Chemical Equation Presented).
A simple and practical method for the oxidation of thiols to disulfides at mild conditions without solvents
He, Ying,Hang, Dongliang,Lu, Ming
experimental part, p. 1118 - 1124 (2012/08/14)
A green, straightforward, and novel method for the oxidation of thiols to the corresponding disulfides is reported using hydrogen peroxide catalyzed by tetrabutylammonium iodide (TBAI) without solvents at room temperature. The corresponding disulfides were obtained with excellent yields and short reaction times. Copyright
CpMn(CO)3-catalyzed photoconversion of thiols into disulfides and dihydrogen
Tan, Kheng Yee Desmond,Kee, Jun Wei,Fan, Wai Yip
experimental part, p. 4459 - 4463 (2011/01/10)
The UV photolysis of CpMn(CO)3 with thiols at room temperature effected the following catalytic transformation: 2 RSH → R 2S2 + H2. This reaction is a cleaner and greener way toward making disulfides, as it produces dihydrogen as the only side-product. The manganese system exhibits high chemoselectivity as the transformation proceeds efficiently even in the presence of numerous functional groups. A manganese dicarbonyl complex, CpMn(CO)2RSH, and cyclopentadiene have also been detected using FTIR and NMR spectroscopic techniques, respectively. Based on our experimental data, a mechanism has been proposed to account for the catalysis.
