What is MERCURY(II) TRIFLUOROMETHANESULFONATE?
The Uses of MERCURY(II) TRIFLUOROMETHANESULFONATE
Hg(OTf)2 exhibits remarkable catalytic activity for the hydroxylative cyclization of 1,6-enynes. Mercuric triflate is a very versatile reagent and has been used for several organic catalytic transformations including C-C bond forming cyclizations, alkyne hydrations, heterocycle synthesis and very recently in C-N bond forming reactions. Commonly used as the metal source for Lewis acid catalyzed asymmetric reactions.
