Nickel-Catalyzed C?H Chalcogenation of Anilines
Müller, Thomas,Ackermann, Lutz
, p. 14151 - 14154 (2016)
The C?H thiolation of aniline derivatives was accomplished with a versatile nickel(II) catalyst under ligand-free conditions. The robust nature of the nickel catalysis system was reflected by the C?H thiolation with a good functional group tolerance and an ample scope, employing anilines possessing removable directing groups. The widely applicable nickel catalyst also allowed for aniline C?H selenylations, while mechanistic studies provided strong support that the rate-determining step is the C?H activation.

Simple reaction conditions and recyclable reagents are crucial for environmentally friendly industrial applications. An environment-friendly, recyclable and economic strategy was developed to synthesize diaryl chalcogenides by the CuCl2-catalyzed C S bondformation reaction via iodobenzenes and benzenethiols/1,2-diphenyldisulfanes using N,N'-dimethylethane-1,2-diamine (DMEDA) as ligand, base, and solvent. For these reactions, especially the reactions of diiodobenzenes and aminobenzenethiols/disulfanediyldianilines, a range of substrates are compatible and give the corresponding products in good to excellent yields. Both of the reagents in the catalytic system (CuCl2/DMEDA) are inexpensive, conveniently separable, and recyclable for more than five cycles.

New spermine and spermidine derivatives as potent inhibitors of trypanosoma cruzi trypanothione reductase
Bonnet, Beatrice,Soullez, David,Davioud-Charvet, Elisabeth,Landry, Valerie,Horvath, Dragos,Sergheraert, Christian
, p. 1249 - 1256 (2007/10/03)
Several spermine and spermidine derivatives containing 2-amino diphenylsulfide substituents were prepared and tested for their inhibiting effects on Trypanosoma cruzi trypanothione reductase. IC50 values were assessed between 0.3 and 3 μM. Compound 32 (K(i) = 0.4 μM) is the most potent TR inhibitor described so far.
