(n-Butyl)triphenylphosphonium bromide（CAS# 1779-51-7) Nā hoʻohana a me nā ʻano hana synthesis
ʻO Butyltriphenylphosphine bromide kahi hui organophosphorus. Loaʻa iā ia nā noi nui i ka synthesis organik, a eia kekahi o kāna mau hoʻohana maʻamau a me nā ʻano hana synthesis:
E hoʻohana:
1. Catalyst: Hoʻohana mau ʻia ka butyltriphenylphosphine bromide ma ke ʻano he catalyst no kekahi mau hopena kemika. No ka laʻana, ma ka hopena Friedel-Gram, hiki iā ia ke hoʻopili i ka hoʻohui ʻana ma waena o nā alkynes a me nā boride e synthesize i nā isomers topological o nā alkynes.
2. Kemika Organometallic: Hiki ke hoʻohana ʻia ka butyltriphenylphosphine bromide ma ke ʻano he ligand ma ke kemika organometallic. Hiki iā ia ke hana i nā mea paʻakikī me nā ion metala a komo i kekahi mau mea koʻikoʻi koʻikoʻi synthesis reactions, e like me Suzuki reaction.
Hana Hana:
Nui nā ʻano hana no ka synthesis o butyltriphenylphosphine bromide, a ʻo kēia kekahi o nā ala maʻamau:
1. ʻO nā mea maka: bromobenzene, triphenylphosphine, butane bromide;
2. Nā ʻanuʻu:
(1) I loko o ka lewa inert, hoʻohui ʻia ka bromobenzene a me ka triphenylphosphine i ka ʻeke pane;
(2) Hoʻopaʻa ʻia ka ʻōmole hopena a hoʻoulu ʻia ma lalo o ka mana o ka mahana, a ʻo ka wela o ka hopena maʻamau he 60-80 degere Celsius;
(3) E hoʻohui mālie i ka butane bromide e like me ka mea e pono ai a hoʻomau i ka hoʻoulu ʻana;
(4) Ma hope o ka pau ʻana o ka pane ʻana, hoʻomaʻalili i ka lumi wela;
(5) Ka unuhi a me ka holoi ʻana me nā solvents, a me ka hoʻomaloʻo ʻana, crystallization a me nā ʻanuʻu lapaʻau ʻē aʻe;
(6) ʻO ka hope, loaʻa ka butyltriphenylphosphine bromide huahana.
