Varsal Introduces Triflates
and Silylated Derivatives
|
|
Warminster, PA - (January 15, 2003)
|
|
Varsal, the world’s leading producer of methanesulfonic
acid and its derivatives, announces the addition of
trifluoromethanesulfonic acid (triflic acid) and
trifluoromethanesulfonic anhydride (triflic anhydride) to its line of
products. Triflates are only available from limited sources worldwide.
|
|
Triflates are one of the best leaving groups for organic
synthesis (SN2 reactions), due to the stabilizing effect of the
fluorine atoms on the anion, and can be extremely useful in chiral
synthesis. When combined with silanes, triflates can be very useful for
silylation of unreactive substrates, such as primary and secondary
alcohols.
|
|
Varsal offers several different silylated triflates,
such as tert-butyldimethylsilyl triflate (TBDMS-triflate) to silylate
tertiary and hindered secondary alcohols; and triisopropylsilyl
triflate (TIPS-triflate) which is especially useful due to the steric
screening provided by the three isopropyl substituents. TIPS-triflate
is also very helpful to silylate primary and secondary alcohols.
