A triflate group is an excellent leaving group used in certain organic reactions such as nucleophilic substitution, Suzuki couplings and Heck reactions. Since alkyl triflates are extremely reactive in SN2 reactions, they must be stored in conditions free of nucleophiles (such as water). The anion owes its stability to resonance stabilization which causes the negative charge to be spread symmetrically over the three oxygen atoms. An additional stabilization is achieved by the trifluor… Web4. nov 2024 · PHENYL TRIFLATE - Physico-chemical Properties. 1.396 g/mL at 25 °C (lit.) 99-100 °C/60 mmHg (lit.) n20/D 1.435 (lit.)
