The successful application of galliumtrichloride as a catalyst for the intermolecular hydroamination of alkynes with aromatic amines is reported. The reaction is effective with many aniline derivatives and shows exclusive selectivity for the Markovnikov products. The mechanism of the transformation was investigated by DFT calculations and a plausible pathway is proposed.

The synthesis of a solid, bench-stable, strong organic Bronsted acid with a computed pK(a) of 0.9 is reported. An X-ray crystal structure and DFT calculations are provided which offer insight into the bonding of this acid. The application of this strong organic Bronsted acid as a catalyst for the intermolecular hydroamination of unactivated alkenes and as an activator for Au(I)-catalyzed alkyne hydroamination with anilines is described.
