4,4'-{2}}Bi-1,3-benzodioxole-5,5'-diylbis(diphenylphosphine) 丨 CAS 210169-54-3

4,4'-Bi-1,3-benzodioxole-5,5'-diylbis(diphenylphosphine) feem ntau yog siv los ua bidentate phosphine ligand hauv homogeneous catalysis. Nws cov txha caj qaum bi-benzodioxole thiab cov khoom siv hluav taws xob nplua nuj diphenylphosphine pawg ua rau nws tsim nyog rau kev tsim cov khoom ruaj khov nrog cov hlau hloov pauv xws li palladium, rhodium, ruthenium, thiab npib tsib xee. Cov hlau complexes yog siv rau hauv kev sib txuas sib txuas, asymmetric hydrogenation, C-C thiab C-N daim ntawv cog lus, thiab olefin transformations. Lub ligand kuj tseem siv rau hauv cov tshuaj zoo synthesis, tshuaj txoj kev optimization, thiab kev txhim kho cov txheej txheem catalytic siab heev uas yuav tsum tau muaj kev tswj xyuas meej ntawm steric thiab hluav taws xob ib puag ncig. Hauv cov chaw tshawb fawb, nws yog ib qho cuab yeej rau kev tsim cov catalysts nrog kev xaiv reactivity thiab high turnover efficiency.

Cov ligand no muaj ntau yam kev ua tau zoo uas ua rau nws muaj kev ntxim nyiam hauv catalytic chemistry. Nws bidentate xwm txhawb chelation muaj zog rau cov chaw hlau, feem ntau ua rau kev txhim kho catalyst stability, lub neej ntev catalyst, thiab txhim khu kev tiv thaiv rau decomposition. Cov txheej txheem steric nyob ib ncig ntawm phosphorus atoms tso cai rau kev tswj kom zoo ntawm kev xaiv catalytic, ua rau nws muaj txiaj ntsig zoo rau kev ua kom zoo dua cov txiaj ntsig hauv cov organic synthesis. Cov hluav taws xob- pub cov yam ntxwv ntawm cov pab pawg diphenylphosphine txhawb kev ua kom zoo ntawm cov substrates thiab txhim kho cov tshuaj tiv thaiv. Tsis tas li ntawd, cov txheej txheem ua kom muaj ntxhiab tsw zoo txo ​​qis kev hloov pauv yooj yim, pab tswj kom zoo -txoj kev sib koom ua ke geometries uas nyiam cov cwj pwm catalytic.
