Methyl trifluoromethanesulfonate

Methyl trifluoromethanesulfonate C화학적 특성, 용도, 생산

화학적 성질

clear colourless to yellow liquid

용도

suzuki reaction

일반 설명

Brown liquid. Insoluble in water.

공기와 물의 반응

Highly flammable. Insoluble in water.

반응 프로필

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.

건강위험

ACUTE/CHRONIC HAZARDS: When heated to decomposition Methyl trifluoromethanesulfonate emits toxic fumes.

화재위험

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. [Hansen J Org Chem 30 4322 1965, Kurz & El-Nasr J Am Chem Soc 104 5823 1982, Beilstein 3 IV 34.]
