Triflyl group
{{short description|Chemical group (–SO2CF3)}}
In organic chemistry, the triflyl group (systematic name: trifluoromethanesulfonyl group) is a functional group with the formula {{chem2|R\sSO2CF3}} and structure {{chem2|R\sS(\dO)2\sCF3}}. The triflyl group is often represented by –Tf.
The related triflate group (trifluoromethanesulfonate) has the formula {{chem2|R\sOSO2CF3}}, and is represented by –OTf.{{cite book | first1 = Michael B. | last1 = Smith | first2 = Jerry | last2 = March | title = March's Advanced Organic Chemistry | publisher = John Wiley & Sons | year = 2007 | edition=6th | isbn = 978-0-471-72091-1 | page = 497 }}
