Niobium Chloride| NbCl5| CAS 10026-12-7| Hoolako Facoty| Maʻemaʻe Kiʻekiʻe 99.9%

ʻO ka wehewehe pōkole:

ʻO ka Niobium(V) chloride, i ʻike ʻia ʻo ka niobium pentachloride, he paʻa kalamele melemele. Hydrolyze ia i ka ea, a ua haumia pinepine nā laʻana me nā mea liʻiliʻi o NbOCl₃. Hoʻohana pinepine ʻia ma ke ʻano he precursor i nā pūhui ʻē aʻe o ka niobium. Hiki ke hoʻomaʻemaʻe ʻia ʻo NbCl₅ e ka sublimation.

Hoʻohana ʻia e hana i nā pūhui chloro-aryloxide i hui pū ʻia, e like me [Nb(OC6H3-2,6-i-Pr2)2Cl3]2, e hana ana i ka pyridine a i ʻole ka phosphine adducts me kahi geometry ʻeono-coordinate distorted.

Hoʻohana ʻia e like me Lewis acid catalyst i ka synthesis organik.

ʻO Niobium(V) chloride ka mea mua i ka hoʻomākaukau ʻana i ka niobium maʻemaʻe, a me ka ferroniobium. Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe Lewis acid i ka synthesis organik i ka hoʻoulu ʻana i nā alkenes i ka hopena carbonyl-ene a me ka hopena Diels-Alder.
