ʻO Lithium trifluoromethanesulfonate, ka mea i ʻike ʻia ʻo LiOTf, he mea koʻikoʻi reagent a me ka catalyst i ka synthesis organik.He paʻakai ia i hana ʻia e ka hui ʻana o nā cation lithium (Li+) a me nā anion trifluoromethanesulfonate (OTf-).Hoʻohana nui ʻia ʻo LiOTf i nā hopena kemika like ʻole ma muli o kāna mau waiwai kūʻokoʻa a me ka hiki ke maʻalahi i nā loli i makemake ʻia.Hiki iā ia ke ho'āla i nā pūʻulu hana like ʻole a me nā substrates, e hāpai ana i nā hopena e pili ana i ka hoʻokumu ʻana i nā paʻa hou.He mea maikaʻi loa ʻo LiOTf i ka hoʻoulu ʻana i nā kaula kalapona-oxygen (CO), e like me ka hopena acetalization, kahi e hoʻomaʻamaʻa ai i ka hoʻokumu ʻana i nā acetals mai nā waiʻona.Hiki iā ia ke hoʻoikaika i nā mea paʻa heteroatom ʻē aʻe, e like me nā paʻa carbon-nitrogen (CN), hiki ke hoʻokumu i nā amides a imines.ʻO ka hoʻohana ʻana i ka LiOTf ma ke ʻano he catalyst e hiki ai ke hoʻololi i nā kūlana ʻoluʻolu, nā koi haʻahaʻa o ka ikehu, a me ka hoʻomaikaʻi ʻana i ka koho.ʻO ka Lithium kahi ion metala pono e hiki ke komo i nā ʻano ʻano like ʻole, e like me ka hoʻohui ʻana i ka metala-catalyzed cross-coupling reactions a me ka nucleophilic substitution reactions.Hāʻawi ʻo LiOTf i kahi kumu kūpono o ka lithium no kēia mau hoʻololi.Eia hou, hiki i ka anion trifluoromethanesulfonate ke lilo i mea kū'ē, e kaulike ana i ka uku o ka lithium cation a me ka hoʻopaʻa ʻana i nā intermediates reactive.Hiki iā ia ke hana ma ke ʻano he mea hoʻoheheʻe hoʻonohonoho, hoʻomaʻamaʻa i nā hopena e pili ana i nā catalysts metala hoʻololi a i ʻole nā mea hana ʻē aʻe.Eia kekahi, hoʻohana pinepine ʻia ʻo LiOTf ma ke ʻano he electrolyte i nā pā lithium-ion ma muli o kona kūpaʻa a me ka conductivity ionic kiʻekiʻe.Pono e mālama ʻia ma kahi maloʻo a maloʻo, ma kahi mamao o ka wai a me nā kumu wela.E like me nā paʻakai lithium ʻē aʻe, loaʻa ʻo LiOTf i kahi pilikia o ka decomposition thermal a hiki ke hana i nā uahi ʻawaʻawa ke ʻike ʻia i nā mahana kiʻekiʻe.ʻO kāna Lewis acidity, hiki ke hāʻawi i nā cation lithium, a me nā waiwai solubilizing i mea waiwai no nā ʻano hoʻololi kemika.Eia nō naʻe, pono e mālama pono i ka mālama ʻana a me ka mālama ʻana i mea e mālama pono ai i ka hoʻohana ʻana.
