(R) -(6,6-Dimethoxy-1,1-biphenyl-2,2-diyl)bis (dicyclohexylphosphine) 丨 CAS 172617-14-0

(R) -(6,6-Dimethoxy-1,1-biphenyl-2,2-diyl)bis (dicyclohexylphosphine) yog ib qho khoom muaj nqis heevchiral diphosphine ligandsiv nyob rau hauv asymmetric catalysis thiab organometallic chemistry. Nws cov pob txha biphenyl txha nraub qaum thiab chiral configuration ua rau nws zoo tagnrho rau kev tsim cov khoom ruaj khov nrog cov hlau hloov pauv xws li palladium, rhodium, thiab ruthenium. Cov hlau-ligand complexes no tau siv dav hauv asymmetric hydrogenation, hydroformylation, allylation, thiab cross-coupling reactions, uas yog qhov tseem ceeb rau kev tsim cov tshuaj ntshiab enantiomerically, agrochemicals, thiab tshuaj zoo. Lub ligand's steric thiab hluav taws xob cov khoom ua rau siab enantioselectivity thiab catalytic efficiency nyob rau hauv ob qho tib si homogeneous thiab industrial-scale cov tshuaj tiv thaiv. Nws kuj tau ua hauj lwm hauv kev tshawb fawb los tsim cov chiral catalysts tshiab, kev tshawb fawb txog kev siv tshuab, thiab tsim cov kev hloov pauv tom ntej - tiam asymmetric.

Lub compound muab cov txiaj ntsig tseem ceeb vim nwstxhav chiral qaum, tunable steric ib puag ncig, thiab kev sib koom ua haujlwm siab. Lub moj khaum biphenyl ua kom cov qauv kev ruaj ntseg thiab meej spatial orientation ntawm phosphine pawg, txhawb siab enantioselectivity hauv catalyzed cov tshuaj tiv thaiv. Cov dimethoxy hloov pauv thiab cov pawg dicyclohexylphosphine loj tuaj yeem ua kom zoo - kho cov teebmeem hauv hluav taws xob thiab steric, txhim kho kev ua haujlwm thiab kev xaiv. Nws zoo heev solubility nyob rau hauv cov organic solvents yooj yim complexation du nrog hlau thiab compatibility nrog ntau yam tshuaj tiv thaiv tej yam kev mob. Tsis tas li ntawd, cov ligand pab txhawb rau siab yields, reproducibility, thiab robustness nyob rau hauv catalytic systems, ua rau nws zoo heev haum rau ob qho tib si kuaj thiab industrial daim ntaub ntawv uas leej asymmetric induction yuav tsum tau.
