Cov Ntawv Thov
Txiav txim siab ntswsFoxonium bromide (CAS 25- Nws yog feem ntau thov rau tiam epoxides los ntawm carbonyl tebchaw los ntawm corey-chaykovsky kev tawm tsam. Tsis tas li ntawd, nws tau siv nyob rau hauv cyclopropanation, aziridination, thiab lwm qhov kev hloov pauv ntawm kev kho mob hauv chav kuaj thiab kev lag luam tshuaj synthesis. Nws cov kev cuam tshuam ua rau nws muaj txiaj ntsig zoo rau kev ua cov tshuaj kiab duab, agnochemicals, thiab zoo cyclic ua qauv.
Cov txiaj ntsig
Cov txiaj ntsig ntawm kev txiav tawm ntawm kev ua txhaum cai Nws sulfonium qauv pab txhawb nqa cov khoom noj khoom haus uas muaj txiaj ntsig me me, tso cai rau kev xaiv kev hloov pauv ntawm epoxides thiab cyclopropanes. Nws yog soluble nyob rau hauv ib txwm organic cov kuab tshuaj thiab tau tshaj tawm cov tshuaj tiv thaiv ntau yam, muab cov khoom siv hluav taws xob hauv hluavtaws. Qhov sib xyaw ua ke tau kev ntseeg tau, tshuaj lom neeg muaj kuab heev, thiab peev xwm los tsim cov khoom siv tswj cov serochemically tswj tau ua rau nws siv tau thiab muaj txiaj ntsig zoo hauv cov etthic synthesis.
Tag
Txo cov neeg siv ntsev tsis zoo yog qhov kev siv tseem ceeb hauv ylide - Kev hloov kho kho me xws li epoxidation thiab cyclopropanation. Nws qhov ruaj khov, kev ua kom muaj yees, thiab kev sib xyaw nrog ntau yam kev tiv thaiv muaj zog ua kom muaj txiaj ntsig zoo ntawm cancules thiab ua haujlwm molecules. Los ntawm kev txhawb nqa kev ua yeeb yam thiab qhov siab {3} Youce cov cuab yeej kev hloov pauv, nws tseem yog ib qho kev tshawb fawb tseem ceeb hauv ob qho kev tshawb nrhiav hauv ob qho.
