Cov Ntawv Thov
1. Nruab nrab hauv cov tshuaj sapticaltical
Siv los ua lub tsev thaiv hauv cov synthesis ntawm cov tshuaj sib txuas ntawm cov chaw siv hluav taws xob, tshwj xeeb:
Hloov chaw benzoates
Aryl esters nrog halogenated pawg ua haujlwm
Lub Bromo thiab Chloro pawg pab xaiv cov ntoo khaub lig-txuas cov kev tawm tsam (piv txwv, heck, lossis inste) los qhia cov pab pawg ntxiv lossis heterozeyl.
2. Agochemical intermediate
Ua haujlwm hauv kev npaj cov fungicides, tshuaj tua kab, thiab tshuaj tua kab.
Lub tshuab hluav taws xob-rho tawm halogens nce bioactivity thiab ib puag ncig ruaj khov ntawm kev ua kom sib xyaw.
3. Cov Khoom Siv Science thiab Tshwj Xeeb Tshuaj
Siv ua cov txheej txheem ua ntej nyob rau hauv cov ntaub ntawv ntawm cov ntaub ntawv ua haujlwm, suav nrog ua kua muaju, UV stabilizers, thiab fluorophores.
Cov pab pawg Ester tso cai rau kev hloov pauv ntxiv rau cov acids, dej cawv, lossis kev tawm tsam.
4. Hla-txuas thiab kev tshawb fawb ua haujlwm
Dav siv nyob rau hauv cov tswv yim hluav taws xob kev tshawb fawb kom kawm Regioselective halogen kev los yog ua haujlwm.
Ib qho tseem ceeb substrate hauv cov qauv kev sib raug zoo (SAR) thiab Lociater Synthesis cov kev kawm.
Cov txiaj ntsig
1. Dual Halogen Kev Ua Haujlwm (Br thiab CL)
Lub xub ntiag ntawm ob lub bromo thiab chloro hloov chaw pub mis nyuj ortus remonity:
Bromine yog ntau reactive nyob rau hauv pd-catalalyzed cross-txuas.
Chlorine tuaj yeem khaws cia lossis ua haujlwm tau zoo rau cov theem tom qab.
Ua rau cov txheej txheem stephnub me me ntawm cov muaj ntxhiab tsw ntxhiab tsw.
2. Khoom siv hluavtaws yooj yim
Pab methyl ester tuaj yeem yog hydrolyzed rau carboxylic acid lossis hloov pauv mus rau kev tawm suab thiab dej cawv, muab ntau yam dej ntws ntau yam.
Tau tshaj nrog ntau yam nucleophilic thiab hluav taws xob kev phiv tshuaj.
3. Cov tshuaj ruaj khov
Ruaj khov nyob rau hauv tus qauv kev mob thiab yooj yim los lis hauv kev kuaj thiab cov chaw ntau lawm.
Haum rau ntau kauj ruam syntheses yuav tsum muaj intermediate ua kom huv thiab khaws cia.
4. Kev Lag Luam Kev Lag Luam
Muaj tshuaj lom neeg muaj cov tshuaj lom neeg hauv kev tshawb fawb-qib thiab cov khoom siv ntau, ua rau nws nkag tau rau R & D thiab cov ntawv thov teev.
Tag
Methyl 2-Bromo-5-chlorobenenzoate (CAS 27-53 yog Halogenated Benzoate Ester siv tau ntau yam ntawm cov tshuaj, agnchemicals, thiab cov ntaub ntawv ua haujlwm. Nws cov pab pawg dual davogen tsim kom muaj kev xaiv ua haujlwm hauv cov khoom siv hluav taws xob niaj hnub, thaum lub sijhawm estericality muab cov hluavtaws ntxiv. Nws lub luag haujlwm hauv kev txhawb nqa kev hla kev sib txuas thiab ua kom muaj ntxhiab tsw ntxhiab ua rau nws muaj txiaj ntsig zoo rau kev kawm thiab kev lag luam chemical.
