Diastereoselective radical alkylations of alkyl aryl sulfoxides
1,2-Asymmetric induction in reactions of arylsulfinylated radicals has been examined and compared to the anionic processes. A rule of thumb allowing to predict the stereoselectivity is presented.

Process for the nucleophilic substitution of unactivated aromatic and heteroaromatic substrates
The nucleophilic substitution upon unactivated monocyclic or polycyclic aromatic or heteroaromatic substrates bearing suitable leaving groups can be achieved by catalyzing the substitution of said leaving groups by an anionic nucleophile with a cyclic or acyclic polydentate chelating ligand. Specific products of this reaction can be used in preparing sulfonylurea herbicides.
