Living polymerizations of internal alkynes (2-hexyne, 3-hexyne, 4-methyl-2-pentyne, and 1-phenyl-1-propyne) have been demonstrated at 50 °C by (arylimido)niobium(V)–alkylidene complex catalysts, Nb(CHSiMe3)(NAr)[OC(CF3)3](PMe3)2 [Ar

Low loaded W-Pd/Alumina are relatively novel catalysts for performing the selective hydrogenation of alkynes, but there is scarce information on the working mechanism. This work studies the kinetics of the selective hydrogenation of 3-hexyne to (Z)-3

The mononuclear unsaturated nickelalactones [Ni{C(Et) C(Et)–COO}(DBU)2] (1) and [Ni{C(Et) C(Et)–COO}(dcpe)] (2) were synthesized by oxidative coupling of CO2 and 3-hexyne at zero-valent nickel in presence of DBU or dpce, respectively. Attempts to

The (Z)/(E) ratio was analyzed for the 3-hexyne semi-hydrogenation at 275, 290 and 303 K. [RhCl(NH2(CH2)12CH3)3] pure and supported on a carbonaceous material were used as catalysts. The supported complex showed high values of conversion and selectiv

The dichlorobis (tridecylamine) palladium(II) complex, pure and supported on γ-Al2O3, was used as catalyst for the semi-hydrogenation of 3-hexyne. The complex was characterized by centesimal composition, XPS and IR. The influence of the temperature

Reaction of [WCl 2 (CO) 3 (NCMe) 2 ] (prepared in situ by reacting [WI 2 (CO) 3 (NCMe) 2 ] with two equivalents of NaCl in acetone) with an excess of EtC 2 Et in CH 2 Cl 2 gives the bis(3-hexyne) complex [WCl 2 (CO)(NCMe)(η 2 -EtC 2 Et) 2 ] ( 1 ). E

Reaction of [MI2(CO)(NCMe)(η2-EtC2Et)2] (M = Mo,W) with one equivalent of 2,2' -bipyridine (bipy) in CH2C12 at room temperature gives either the neutral complex, [MoI2(CO)(bipy)- (η2-EtC2Et)] (1) or the cationic complex, [WI(CO)(bipy)(η2-EtC2Et)2]

3-Hexyne has been adsorbed on Ru(0001) at different temperatures under ultrahigh vacuum. At 100 K and very low coverage (0.05 L), the reflection−absorption infrared (RAIR) spectrum is consistent with the formation of a surface di-σ/π complex invo
