Descrizione generale

Methyl trifluoromethanesulfonate is a strong methylating reagent, commonly used for the pre-methylation of polysaccharides under mild basic conditions.

Applicazioni

Methyl trifluoromethanesulfonate can be used as a methylation reagent:
  • In the determination of polysulfides, zerovalent sulfur in sulfide-rich water wells, and polysulfide species in electrolyte of a lithium–sulfur battery using chromatography-based techniques.
  • In reactions with potassium enolates.
  • For the conversion of amines to methyl ammonium triflates.

Two cationic carbene complexes with no heteroatom in the ring containing the carbene carbon, trans-bromo(2-methyl-2,6-dihydroisoquinolin-6-ylidene)bis(triphenylphosphine)palladium(II) triflate (3) and trans-chloro(1,2-dimethyl-1,7-dihydroquinolin-7-ylidene)bis(triphenylphosphine)palladium(II) triflate (4), were synthesized by oxidative substitution of Pd(PPh3)4 with N-methylated 6-bromoisoquinolinium and 7-chloro-2-methylquinolinium cations, respectively. Compound 3 was also prepared
