Catalytic, -Selective, Semi-Hydrogenation of Alkynes with a Zinc-Anilide Complex.

The reversible activation of dihydrogen with a molecular zinc anilide complex is reported. The mechanism of this reaction has been probed through stoichiometric experiments and density functional theory (DFT) calculations. The combined evidence suggests that H activation occurs by addition across the Zn-N bond a four-membered transition state in which the Zn and N atoms play a dual role of Lewis acid and Lewis base.

Background: Previous research has sought to adopt the use of drift-reducing technologies (DRTs) for use in field trials to control diamondback moth (DBM) Plutella xylostella (L.) (Lepidoptera: Plutellidae) in canola (Brassica napus L.).
