Anion Controlled Stereodivergent Semi-Hydrogenation of Alkynes using Water as Hydrogen Source

Kangkui Li et al.

Summary: A stereodivergent semi-hydrogenation of alkynes controlled by anions is reported, catalyzed by low-cost and stable nickel(II) salts with water as a friendly hydrogen source and zinc powder as a metal reductant. The anion of the nickel(II) salt plays a crucial role in controlling the stereoselectivity of the reaction, allowing for the convenient preparation of trans- and cis-alkenes under mild conditions. The reaction mechanism is proposed to involve water as the hydrogen donor based on control experiments.

Manganese-Catalyzed Dehydrogenative Silylation of Alkenes Following Two Parallel Inner-Sphere Pathways

Stefan Weber et al.

Summary: A novel manganese(I)-catalyzed dehydrogenative silylation reaction was reported, using an alkyl bisphosphine manganese(I) complex as the most active precatalyst. The reaction efficiently converted a variety of aromatic and aliphatic alkenes to their corresponding products with high selectivity at room temperature. Insights into the mechanism were provided based on experimental data and DFT calculations, revealing two parallel reaction pathways.

Ruthenium-Catalyzed E-Selective Partial Hydrogenation of Alkynes under Transfer-Hydrogenation Conditions using Paraformaldehyde as Hydrogen Source

Marcus N. A. Fetzer et al.

Summary: E-alkenes were synthesized with up to 100% E/Z selectivity via ruthenium-catalyzed partial hydrogenation of different aliphatic and aromatic alkynes under transfer-hydrogenation conditions. The use of paraformaldehyde as a safe and cheap solid hydrogen carrier, along with water, for transfer-hydrogenation of alkynes was optimized with the binuclear [Ru(p-cymene)Cl-2](2) complex and BINAP ligand. Mechanistic investigations revealed that the E-selectivity in this reaction is due to the fast Z to E isomerization of the formed alkenes.

Zhidao Huang et al.

Summary: This study reports a coordination-induced ionic monohydride mechanism for Z-selective semihydrogenation of alkynes with ethanol, which selectively reacts with alkynes over the corresponding Z-alkenes. The key role of an amine in promoting alcoholysis is essential for the monohydride mechanism, demonstrating excellent performance in terms of substrate scope, generality, and compatibility.

Catalytic Hydrogenation of Alkenes and Alkynes by a Cobalt Pincer Complex: Evidence of Roles for Both Co(I) and Co(II)

Hussah Alawisi et al.

Summary: This study investigates the activity of cobalt complexes in catalyzing the hydrogenation of alkenes and semi-hydrogenation of alkynes, highlighting the importance of the shuttling between Co(I) and Co(III) states in the reaction mechanism. The generation of small quantities of Co(II) during catalytic turnover is found to be responsible for the observed isomerization in alkyne semi-hydrogenation.

Hydroboration of Terminal Alkenes and trans-1,2-Diboration of Terminal Alkynes Catalyzed by a Manganese(I) Alkyl Complex

Stefan Weber et al.

Summary: The Mn-catalyzed hydroboration of terminal alkenes and the 1,2-diboration of terminal alkynes with pinacolborane have been successfully achieved. The most active pre-catalyst is a bench-stable alkyl bisphosphine Mn-I complex. The catalytic process involves migratory insertion of a CO ligand into the Mn-alkyl bond to yield an acyl intermediate, which further undergoes B-H bond cleavage or C-H bond cleavage for alkenes and alkynes, respectively, forming active Mn-I boryl and acetylide catalysts.
