An unprecedented substrate-directed, iridium-catalyzed enantioselective hydroalkynylations of trisubstituted alkenes to form acyclic all-carbon quaternary stereocenter β to a nitrogen atom was reported. The hydroalkynylation of enamide occurred with unconventional selectivity, favoring the more hindered reaction site. Homopropargyl amides with β-stereocenters were prepared in high regio- and enantioselectivities. Combined exptl. and computational studies revealed the origin of the regio- and enantioselectivities.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1365531-93-6, is researched, Molecular C52H60O4P2, about Oligomerization of Ethylene Using a Diphosphine Palladium Catalyst, the main research direction is palladium diphosphine catalyst preparation oligomerization ethylene; oligomer ethylene unsaturated preparation hydrogenation palladium diphosphine catalyst.COA of Formula: C52H60O4P2.

The palladium diphosphine complex converts ethylene to hyperbranched unsaturated oligomers (Mn ≈ 330 g/mol) at 22 °C. In addition to the high stability of this catalyst observed at temperatures up to 75 °C, an increase of the reaction temperature leads to a decrease in branching densities of the oligomers, in sharp contrast to the palladium and nickel diimine catalyst systems. One-pot oligomerizations/hydrogenations were carried out to form hyperbranched saturated oligomers.
