Abstract
A palladium-catalyzed, enantioselective, aryl-aryl cross-coupling reaction using 1-naphthyldimethylsilanolates and chiral bis-hydrazone ligands has been developed. A family of glyoxal bis-hydrazone ligands containing various 2,5-diarylpyrrolidine groups was prepared to evaluate the influence of ligand structure on the rate and enantioselectivity of the cross-coupling. New synthetic routes to the 1-amino-2,5-diarylpyrrolidines were developed to enable the structure/reactivity-selectivity studies. Role reversal experiments of aryldimethylsilanolates and aryl bromides result in biaryl products with the same configuration and similar enantioselectivities implying that reductive elimination is the stereodetermining step. The origin of stereoselectivity is rationalized through computational modeling of diarylpalldium(II) complex which occurs through a conrotatory motion for the two aryl groups undergoing C-C bond formation.

Abstract
Nickel-catalysed P–H/C–CN cross coupling reactions take place efficiently under mild reaction conditions affording the corresponding sp2C–P bonds. This transformation provides a convenient method for the preparation of both arylphosphines and arylphosphine oxides from the readily available P–H compounds and arylnitriles.

Abstract
In the title compound, C28H19F3O4S, a new 2′-benzyloxy (R)-BINOL derivative containing a trifluoromethanesulfonate group in the 2-position, the planes of the two naphthyl ring systems (r.m.s. deviations = 0.012 and 0.019 Å) are at an angle of 73.36 (2)°, and the planes of the benzyl ring and the naphthyl ring system bound to the ether O atom are at an angle of 75.67 (4)°. In the crystal, molecules are linked via C—H⋯F hydrogen bonds, forming chains propagating along [100]. The chains are linked via a weak C—F⋯π interaction and weak π–π interactions [shortest inter-centroid distance = 3.9158 (12) Å], forming a three-dimensional structure. The absolute structure of the molecule in the crystal was determined by resonant scattering [Flack parameter = 0.02 (6)].

Abstract
![]()
Copper(I)
and nickel(0) complexes catalyze the formal [4 + 2] cycloaddition
reactions of 1,2-diazines and siloxyalkynes, a reaction hitherto best
catalyzed by silver salts. These catalysts based on earth abundant
metals are not only competent, but the copper catalyst, in particular,
promotes cycloadditions of pyrido[2,3-d]pyridazine
and pyrido[3,4-d]pyridazine, enabling a new synthesis
of quinoline and isoquinoline derivatives, as well as the formal [2
+ 2] cycloaddition reaction of cyclohexenone with a siloxyalkyne.

Abstract
Phosphines are an important class of ligands in the field of metal-catalysis. This has spurred the development of new routes toward functionalized phosphines. Some of the most important C–P bond formation strategies were reviewed and organized according to the hybridization of carbon in the newly formed C–P bond.
