ʻO ka trifluoromethanesulfonic acid (CF3SO3H), ka mea i ʻike nui ʻia he triflic acid, he ʻakika ikaika a ikaika loa e loaʻa ai ka hoʻohana nui ʻana i nā kaʻina hana a me nā ʻoihana.Hoʻohana nui ʻia ʻo ia ma ke ʻano he catalyst, solvent, a me ka reagent ma muli o kona acidity kūikawā a me nā waiwai kūikawā.Ua manaʻo ʻia ʻo ia kekahi o nā waikawa Brønsted ikaika loa i ʻike ʻia, ʻoi aku ka nui o ka sulfuric, hydrochloric, a me ka fluorosulfuric acid ma ke ʻano o ka acidity.Hiki i kēia acidity kupaianaha ke hiki i ka triflic acid ke hoʻololi i nā hopena like ʻole e koi ai i nā kūlana waikawa ikaika, me ka esterification, acylation, alkylations, a me nā hoʻonohonoho hou.He mea waiwai nui ia no ka paipai ʻana i nā hopena e pili ana i ka carbocations, no ka mea, hoʻopaʻa a hoʻonui i ko lākou reactivity. Hoʻohana pū ʻia ʻo Triflic acid ma ke ʻano he mea hoʻoheheʻe no kekahi mau hopena, ʻoi aku ka nui o ka poʻe e koi ana i nā kaiapuni acidic.Hiki iā ia ke hoʻoheheʻe i ka laulā o nā mea hoʻohuihui a me nā mea hoʻoheheʻe ʻole, i mea e pono ai no nā hopena e pili ana i ka polar a me ka nonpolar solutes.Eia kekahi, hiki i kona ʻano acidic ikaika ke hoʻonui i ka solubility a kōkua i nā kinetics reaction.Hiki i ka ʻakika Triflic ke hana me nā waiʻona, nā amine, a me nā nucleophiles ʻē aʻe e hana i kā lākou triflates like (CF3SO3-), he mau pūʻulu hana paʻa loa.Hiki i nā Triflates ke lawelawe ma ke ʻano he hui haʻalele maikaʻi a hoʻāla paha i nā nucleophiles, e hiki ai i nā ʻano hopena like ʻole e like me ka nucleophilic substitutions, rearrangements, a me carbon-carbon bond formations.ʻO kona ʻano hana kū hoʻokahi a me ka ʻakika e lilo ia i mea waiwai nui no ka hoʻokumu ʻana i nā molekala organik paʻakikī.Eia hou, hiki iā ia ke hōʻike i ka reactivity koho, hiki iā ia ke kuhikuhi i nā pūʻulu hana kūikawā a i ʻole nā ​​kūlana i loko o kahi mole, e hoʻomaʻamaʻa i ka synthesis o nā isomers a i ʻole enantiomers kikoʻī. .Pono e mālama ʻia nā hana palekana kūpono, me ka hoʻohana ʻana i nā mea pale a me ka hana ʻana ma lalo o ka ea kūpono, e hōʻemi i nā pilikia.ʻO kāna acidity ikaika loa e hiki ai iā ia ke catalyze i nā ʻano like ʻole, hana e like me ka solvent, a komo i ka hoʻokumu ʻana i nā pūʻulu hana paʻa.ʻO kāna versatility a me ka reactivity e lilo ia i mea pono ʻole no ka synthesis o nā molekala organik paʻakikī.Eia nō naʻe, pono e mālama ʻia ka mālama ʻana i ka triflic acid, ka mālama ʻana i nā protocol palekana kūpono e hōʻoia i ka maikaʻi o ka chemist a pale i nā pōʻino.
