Ligand-Controlled Regiodivergent Nickel-Catalyzed Hydrocyanation of Silyl-Substituted 1,3-Diynes

A regiodivergent nickel-catalyzed hydrocyanation of 1-aryl-4-silyl-1,3-diynes is reported. When appropriate bisphosphine and phosphine-phosphite ligands are applied, the same starting materials can be converted into two different enynyl nitriles with good

Electronic Effect of Ligands on the Stability of Nickel-Ketene Complexes

Electronically variant (dppf)Ni(ketene) complexes were synthesized and characterized to perform kinetic analysis on their decomposition through a decarbonylation/disproportion process to Ni-CO complexes and alkenes. Ligands containing electron-donating groups stabilized such complexes, whereas an electron-withdrawing group was found to destabilize them. Hammett analysis on the decomposition reaction revealed the buildup of negative charges in the rate-determining step, which corroborates past computational models.

Effects of bidentate phosphine ligands on syn - Anti isomerization in π-allylpalladium complexes

The rates of syn-anti isoinerization in a series of cationic π-allylpalladium complexes [Pd(η3-Me2CCHCHD)(bisphosphine)]BArF4 [ArF = 3,5-(CF3)2C6H3] were measured by 1H NMR spin-saturation transfer techniques. For the complexes with α,ω-bis(diphenylphosphino)-alkanes (Ph2P(CH2)nPPh2, n = 2-4), a correlation between the bisphosphine's bite angles and the syn-anti isomerization rates was observed, the bisphosphine with smaller bite angle accelerating the syn-anti isomerization. The isomerization rate was also dependent on the electronic characteristics of the bisphosphine ligands. Of the substituted dppf ligands (Fe(η5-C5H4PAr2)2, Ar = 4-CF3C6H4, Ph, 4-MeOC6H4), it was fastest with the electron-withdrawing 4-CF3C6H4 group and slowest with the electron-releasing 4-MeOC6H4 group on the phosphorus atoms. These bisphosphines were used as supporting ligands for the palladium-catalyzed allylic alkylation of (Z)-cinnamyl acetate and (Z)-2-hexenyl acetate with the sodium salt of dimethyl methylmalonate. The alkylation products with E-geometry, which result from the isomerization of π-allylpalladium intermediates from anti to syn, were formed more with the bisphosphines of faster syn-anti isomerization.
