Knowing that the Ka of triflic acid (monoprotic) is 8. A clean and efficient and metal-free diacetoxylation reaction of alkenes using commercially available peroxyacids as the oxidants is catalyzed by triflic acid. The balanced equation for this reaction is written as CaCO3 + 2 HCl = CO2 + CaCl2 + H2O. zation is initiated by the trace amount of the triflic acid formed by the hvdrolysis of a much stronger decrease of charge density on H-atoms (1%(4) relative to C Triflic acid (0. The condensation follows a similar pathway, at a similar rate, in the presence or in the absence of D 4. It is hazardous, so the first aid measures and others should be known. Find catalogue prices, chemical data, technical specifications and MSDS documents. Article No. It is one of the strongest acids commercially available. 119 mol) was then added and the reaction mixture was again stirred for 24 hours. In our study, we have found that these additives actually do not activate the phosphine oxide, but activate the silane reducing agent instead. A low concentration of triflic acid and control of the reaction temperature help to tolerate functional groups, such as methoxyl substitution on aromatics.
