Triisopropylsilyl Group - an overview ScienceDirect Topics

WebIn organic chemistry, triflate(systematic name: trifluoromethanesulfonate), is a functional groupwith the formulaR−OSO2CF3and structureR−O−S(=O)2−CF3. The triflate group is often represented by −OTf, as opposed to −Tf, which is the triflyl group, R−SO2CF3. For example, n-butyltriflate can be written as CH3CH2CH2CH2OTf. WebHalogen substituents are easily accommodated, using the names: fluoro (F-), chloro (Cl-), bromo (Br-) and iodo (I-). For example, (CH 3) 2 CHCH 2 CH 2 Br would be named 1-bromo-3-methylbutane. If the halogen is bonded to a simple alkyl group an alternative "alkyl halide" name may be used. clickserve.dartsearch.net remove 2022
