TCFH

TCFH (N,N,N’,N’-tetramethylchloroformamidinium hexafluorophosphate) is an electrophilic amidine reagent used to activate a number of functional groups (such as carboxylic acids) for reaction with nucleophilies. TCFH is most commonly used to activate carboxylic acids for reaction with amines in the context of amide bond formation and peptide synthesis.
