In contrast to traditional metal-based oxidative systems the developed homo-coupling of aryl boronic acids or potassium aryltrifluoroborates uses molecular oxygen or iodine as the oxidant, respectively.

The first catalytic asymmetric aminotrifluoromethylation of alkenes by using Togni′s reagent (II) has been developed.

Title compounds (III) are prepared by TosOH-catalyzed reaction of aromatic aldehydes with (substituted) thiobarbituric acid.

A novel azidative cycloisomerization of homoallenyl amides (I) and (III) using TmsN3 as the azidation reagent and a hypervalent iodine reagent as the oxidant giving a series of azidomethyl-furans (II) and (IV), resp., is presented.

Several C-3a-substituted pyrroloindolines are obtained by nucleophilic substitution reaction of appropriate pyrroloindolinol trichloroacetimidates utilizing anilines, alcohols, thiols, and carbon nucleophiles.

The novel reaction conditions allow the direct mono-N-alkylation of primary aromatic amines.
