Pyridine-4-boronic acid (CAS # 1692-15-5) chiyambi
4-Pyridine boronic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha 4-pyridine boronic acid:
Ubwino:
- Maonekedwe: 4-pyridine boronic acid ndi olimba crystalline colorless.
- Kusungunuka: Kusungunuka m'madzi ndi zosungunulira wamba monga ma alcohols, ethers, ndi ketoni.
- Kukhazikika: 4-Pyridine boronic acid imakhala yokhazikika kutentha kwa firiji, koma kuwonongeka kungachitike pamaso pa kutentha kwakukulu, kupanikizika kwakukulu, kapena ma oxidants amphamvu.
Gwiritsani ntchito:
- Catalyst: 4-pyridylboronic acid angagwiritsidwe ntchito ngati chothandizira mu organic synthesis zimachitikira, monga CC chomangira mapangidwe zimachitikira ndi makutidwe ndi okosijeni zimachitikira.
- Coordination reagent: Lili ndi maatomu a boron, ndipo 4-pyridylboronic acid ingagwiritsidwe ntchito ngati coordination reagent ya ayoni zitsulo, imagwira ntchito yofunika kwambiri pa catalysis ndi machitidwe ena a mankhwala.
Njira:
- 4-Pyridine boronic acid imatha kupezeka pochita 4-pyridone ndi boric acid. The enieni anachita zinthu zidzasinthidwa malinga ndi mmene zinthu zilili.
Zambiri Zachitetezo:
- 4-Pyridine boronic acid ndi organic pawiri, komabe ndikofunikira kusamalira kusamalira bwino. Magalasi oteteza ndi magolovesi ayenera kuvala kuti agwire ntchito.
- Pewani kukhudza khungu ndi kupuma fumbi. Ngati mwakhudza khungu mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri.
- Mukamagwiritsa ntchito ndikusunga, samalani kuti musagwirizane ndi ma okosijeni amphamvu ndi ma asidi amphamvu kuti musayambitse zinthu zoopsa.
- Potaya zinyalala, ziyenera kutayidwa motetezedwa motsatira malamulo amderalo.
