Cov mis mos molecular ntawm Pyridinium Poly (hydrogenfluoride) yog C5H6FN, thiab qhov hnyav molecular yog 99.1062. Nws lub cev thiab cov khoom siv tshuaj muaj xws li qhov ntom ntawm 1.1, qhov kub ntawm 115.3 degree ntawm 760 mmHg, thiab lub teeb nyem ntawm 20 degree. Cov khoom no ua rau nws muaj kev ruaj ntseg zoo thiab rov ua haujlwm raws li cov xwm txheej tshwj xeeb, thiab nws tsim nyog rau ntau yam tshuaj tiv thaiv thiab kev siv hauv kev lag luam.

Cov ntaub ntawv yooj yim

Siv

Organic synthesis cov tshuaj tiv thaiv
Kev npaj ntawm fluoroamines: Kev npaj ntawm -fluoroamines los ntawm cov amino cawv, tseem ceeb hauv kev lag luam tshuaj chemistry.
Acetylene fluorination: Koom nrog acetylene fluorination los ua cov fluorinated alkynes, ua cov organic synthesis nruab nrab, tuaj yeem hloov mus ua cov organic fluorides.
Phenol fluorination: Siv nrog hypervalent iodine (III) reagents rau para-substituted fluorination ntawm phenol los npaj cyclohexadienone, uas muaj peev xwm muaj nuj nqis hauv tshuaj synthesis.
Raws li ib tug fluorination reagent: Nws yog dav siv nyob rau hauv lub fluorination nplhaib-qhib cov tshuaj tiv thaiv ntawm oxygen-muaj thiab nitrogen-muaj peb-membered rings (xws li epoxyfluorination nplhaib-qhib), nrog mob me me, siab stereoselectivity thiab yield.
Silyl ether tiv thaiv pab pawg deprotection cov tshuaj tiv thaiv: Cleavage ntawm silyl ether tiv thaiv pawg cawv, tuaj yeem xaiv cais cov silyl ether.
N-Boc daim ntawv cog lus cleavage cov tshuaj tiv thaiv: Cleavage ntawm N-Boc daim ntawv cog lus, thiab tseem tuaj yeem xaiv cleave silyl ethers nyob rau hauv nws lub xub ntiag, uas yog siv rau kev sib txuas thiab kev hloov kho ntawm cov organic molecules complex.
