1 Μαρ 2004 · The interaction of 1 mol% of triflic acid (trifluoromethanesulfonic acid) with a range of N-substituted N-tert butylcarbamates in acetonitrile results in the removal of the tert-butyl group...
27 Οκτ 2017 · This page by Professor Hans Reich (UW-Madison) provides a collection of common structural motifs in Organic Chemistry and their corresponding pKa values.
15 Σεπ 2006 · Alternate Name: triflic acid. Physical Data: bp 162 °C/760 mmHg, 84 °C/43 mmHg, 54 °C/8 mmHg; d 1.696 g cm −3 . Solubility: sol water and in many polar organic solvents such as DMF, sulfolane, DMSO, dimethyl sulfone, acetonitrile; sol alcohols, ketones, ethers, and esters, but these generally are not suitable inert solvents (see below).
Trifluoromethanesulfonic acid | CHF3O3S | CID 62406 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
With a Ka = 5 × 1014, p Ka = −14.7 ± 2.0, [1] triflic acid qualifies as a superacid. It owes many of its useful properties to its great thermal and chemical stability. Both the acid and its conjugate base CF 3 SO −.
Experimental in this sense means "based on physical evidence". This experimental parameter is called "the pKa". The pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50.
