Hoʻolauna
ʻO 1,8-Diazabicyclo [5.4.0] undec-7-ene, i ʻike maʻamau ʻia ʻo DBU, he mea koʻikoʻi koʻikoʻi.
ʻAno:
1. ʻO ke ʻano a me ke ʻano: He wai kala ʻole a maopopo. Loaʻa iā ia kahi ʻala ammonia ikaika a me ka hoʻoheheʻe ʻana i ka wai.
2. Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe maʻamau, e like me ka ethanol, ether, chloroform, a me dimethylformamide.
3. Paʻa: He kūpaʻa a hiki ke mālamaʻia no ka manawa lōʻihi i ka mahana wela.
4. Hiki i ke ahi: He mea wela ia a pono e pale ʻia mai ka launa pū ʻana me nā kumu ahi.
Hoʻohana:
1. Catalyst: He kumu ikaika ia i hoʻohana mau ʻia ma ke ʻano he catalyst alkaline i ka synthesis organik, ʻoi aku ka nui o nā hopena condensation, nā hoʻololi hoʻololi, a me nā hopena cyclization.
2. Mea hoʻololi Ion: hiki ke hana i nā paʻakai me nā ʻakika organik a lawelawe ma ke ʻano he mea hoʻololi anion, hoʻohana mau ʻia i ka synthesis organik a me ke kemika analytical.
3. Nā mea hoʻopaneʻe kemika: hoʻohana mau ʻia i loko o ka hydrogenation reactions, deprotection reactions, a me amine substitution reactions catalyzed by strong bases in organic synthesis.
Hanana:
Hiki ke loaʻa iā ia ma ka hana ʻana i ka 2-Dehydropiperidine me ka amonia. He mea paʻakikī ke ʻano hana synthesis a koi pinepine i kahi keʻena synthesis organik e hoʻokō.
ʻIke palekana:
1. Loaʻa ka ʻinoʻino a hiki ke hoʻonāukiuki i ka ʻili a me nā maka. I ka wā e hoʻohana ai, pono e hoʻohana ʻia nā mīkina lima pale a me nā maka aniani e pale aku ai i ka hoʻopili pololei ʻana.
2. I ka mālama ʻana a me ka hoʻohana ʻana i nā DBU, pono e mālama ʻia kahi kaiapuni maikaʻi e hoʻemi i ka ʻike o nā mea ʻala a me nā mahu.
3. E hō'ole i ka ho'opili 'ana me nā mea ho'ohāhā, nā'akika, a me nā pūhui mea ola, a pale i ka hana ma kahi kokoke i nā kumu ahi.
4. I ka lawelawe ʻana i ka ʻōpala, e ʻoluʻolu e mālama i nā lula kūloko a me nā kaʻina hana palekana.
