Hoʻolauna
ʻO 2-Bromo-4-fluorobenzaldehyde he mea hoʻohuihui.
ʻAno maikaʻi:
ʻO 2-Bromo-4-fluorobenzaldehyde he paʻa keʻokeʻo keʻokeʻo me kahi ʻala benzaldehyde. Aneane hiki ʻole ke hoʻoheheʻe ʻia i loko o ka wai ma ka lumi wela, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ʻawaʻawa, eter, a me nā ketones.
E hoʻohana:
ʻO 2-Bromo-4-fluorobenzaldehyde ka nui o nā noi i ka synthesis organik.
Hanana:
ʻO ke ʻano synthesis o 2-bromo-4-fluorobenzaldehyde ka mea i loaʻa ma ka hopena o ka fluoroborate a me ka bromobenzaldehyde. ʻO nā ʻanuʻu kikoʻī e pane i ka fluoroborate a me ka bromobenzaldehyde ma lalo o nā kūlana acidic e loaʻa ai ka 2-bromo-4-fluorobenzaldehyde, a laila e hana i kekahi mau hana lapaʻau e loaʻa ai ka huahana i makemake ʻia.
ʻIke palekana: He mea pōʻino ia i hiki ke hōʻino i ke kino kanaka a me ke kaiapuni. Ke hoʻopili ʻia me ka ʻili a me nā maka, hiki iā ia ke hoʻonāukiuki a me ke ʻano wela. I ka hana ʻana, pono e hoʻohana ʻia nā mea pale kūpono e like me nā aniani palekana, nā mīkina lima a me nā lole pale. I ka mālama ʻana, pono e hoʻopaʻa paʻa ʻia a paʻa i ke ahi a me nā kumu wela.
