| Methyl trifluoromethanesulfonate Usage And Synthesis |
| Chemical Properties | clear colourless to yellow liquid | | Uses | suzuki reaction | | Uses | Methyl trifluoromethanesulfonate is used as a powerful methylating reagent in chemistry. Further, it is used in the conversion of amines to methyl ammonium triflates. In addition, it is also used in Suzuki reaction. | | Uses | Methyl trifluoromethanesulfonate was used in the synthesis of 2-Benzyloxy-1-methylpyridinium trifluoromethanesulfonate. | | General Description | Brown liquid. Insoluble in water. | | Air & Water Reactions | Highly flammable. Insoluble in water. | | Reactivity Profile | Methyl trifluoromethanesulfonate is sensitive to heat. . Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. | | Health Hazard | ACUTE/CHRONIC HAZARDS: When heated to decomposition Methyl trifluoromethanesulfonate emits toxic fumes. | | Fire Hazard | Methyl trifluoromethanesulfonate is combustible. | | Purification Methods | Methyl trifluoromethanesulfonate (methyl triflate) [333-27-7] M 164.1, b 97 -97.5o/736mm, 9 9o/~760mm, 100-102o/~760mm, d 4 1.496, n D 1.3238. It is a strong methylating agent but is corrosive and POISONOUS. Fractionate it carefully and collecting the middle fraction (use an efficient fume cupboard) and keep away from moisture. It is a POWERFUL ALKYLATING AGENT and a strong IRRITANT. [IR: Gramstad & Haszeldine J Chem Soc 173 1956 , J Chem Soc 4069 1957 .] Trifluoromethanesulfonic acid (triflic acid) [1493-13-6] M 151.1, boils higher (b 162o/atm), has a pKa of 3.10, and is TOXIC and hygroscopic.
