Versatile syntheses of optically pure PCE pincer ligands : facile modifications of the pendant arms and ligand backbones
A series of chiral C-stereogenic PCP and PCN ligand precursors were prepared in situ from inexpensive achiral starting materials via a simple catalytic asymmetric P–H addition reaction in good overall yields. This facile ...
Palladium catalyzed asymmetric hydrophosphination of α,β- and α,β,γ,δ-unsaturated malonate esters : efficient control of reactivity, stereo- and regio-selectivity
Both PC-cyclometalated and PCP-pincer type palladium catalysts have recently been found to be robust and efficacious catalysts for the asymmetric P–H addition reaction involving activated olefins. Our studies on the ...
Mechanistic insights into the PdII-catalyzed chemoselective N-demethylation vs. cyclometalation reactivity pathways in 1-Aryl-N,N-dimethylethanamines
Two structurally isomeric substituted N,N-dimethylethanamines have been prepared. Treatment of the 2,4-di-tert-butylphenyl isomer with PdII ions generated the ortho-metalated complexes. On the other hand, treatment of the ...
A one-pot diastereoselective self assembly of C-stereogenic copper(I) diphosphine clusters
C-chirogenic diphosphine-based clusters with 8-membered “chairlike” Cu4Cl4L2 and 12-membered “drumlike” Cu6Cl6L3 (L = diphosphine) frameworks were prepared in one-pot syntheses from chiral diphosphines, which were generated ...
