Cov Ntawv Thov
1. Ligand thiab catalyst tsim
Siv los ua nkauj chairal lossis achiral lighad prefursor hauv cov asymmetric catalysis.
Cov ntaub ntawv ib feem ntawm lub nraub qaum hauv kev tsim biphenol-based ligands xws li taum (1,1'-bi-2-naphthol) derivatives.
Ligands muab tau los ntawm biphenols tau siv dav hauv enantioselective kev tawm tsam zoo li asymmetric hydrogenation, allylation, thiab epoxidation.
2. Kws Tshuaj Nruab Nrab Nruab Nrab
Ua haujlwm raws li lub tsev thaiv cov tsev nyob hauv cov synthesation ntawm bioaction molecules thiab kws tshuaj, tshwj xeeb tshaj yog cov uas yuav tsum tau Phenum Moog.
Ua raws li tus yuam sij nruab nrab rau kev npaj cov antioxidants, cov neeg sawv cev tua kabmob, thiab cov neeg tsis muaj peev xwm.
3. Polymer thiab Cov Khoom Siv Kev Tshawb Fawb
Siv nyob rau hauv synthesis ntawm polyphenolic resins thiab kev ua haujlwm siab polymers.
Hydroxyl pawg ua rau hla kev sib txuas lossis ua haujlwm raws li cov chaw uas rov qab kho rau polymer kev hloov kho.
Muab cov tshuaj kom huv si thermal ruaj khov thiab tshuab ua zog hauv cov ntaub ntawv polymeric.
4. Organic synthesis nruab nrab
Pab tau rau kev npaj ntawm biaubyl tebchaw thiab cov muaj ntxhiab tsw muaj ntxhiab.
Tuaj yeem ua haujlwm ntxiv ntawm electrophilic hloov kev, etherification, lossis Esterification.
Cov txiaj ntsig
1. Phenolic Hydroxyl Pawg
Ob pawg hydroxyl ntawm Ortho txoj haujlwm muab cov khoom siv hydrogen muaj zog thiab ua los ntawm cov chaw chelation rau hlau ions.
Qhov no ua rau nws cov nqi hluav taws xob hauv catalyst thiab ligand kev loj hlob.
2. Cov qauv nteg biphenyl
Lub Biphenyl lub moj khaum tau lees paub cov qauv hluav taws xob thiab cov teeb meem, muaj txiaj ntsig zoo rau cov kev siv catalyatic hauv catalytic.
Cov qauv tswj hwm txhim kho lub thermal thiab tshuaj uas muaj kev ruaj ntseg ntawm cov ntaub ntawv thiab ligands.
3. Versatility hauv Tshuaj Kho Mob
Cov pab pawg hydroxyl tso cai rau ntau yam kev hloov kho tshuaj lom zem ua kom sib npaug ntawm solubility, reactivity, thiab cov khoom siv khi.
Yuav derivatized los tsim cov neeg uas ua kom muaj kev ua neej, thiab lwm pab pawg ua haujlwm raws li yuav tsum tau ua.
4. Kev lag luam muaj thiab kev ruaj khov
Npaj tau yooj yim thiab ruaj khov nyob rau hauv kev kuaj ib txwm muaj, ua rau nws siv rau kev tshawb fawb thoob plaws thiab kev lag luam siv.
Tag
2,2 '-Biphenol (CAS 1806-29-7) yog cov muaj txiaj ntsig zoo di-phenolic compound fydroting pawg ntawm 2-txoj haujlwm ntawm lub biphenyl core. Nws ua haujlwm ua ib qho kev sib txuam ntau rau kev synthesis, kev txhim kho cov ntaub ntawv, thiab cov ntaub ntawv loj heev. Nws tshwj xeeb ua ke ntawm rigidity, reactivity, thiab hlau-khi muaj peev xwm ua rau nws tseem ceeb hauv cov asymmetric catalysis, khoom siv science, thiab synthic synthesis.
