Triethylamine → 3,5-Di-tert-butylphenyl methanesulfonate

Participants

Reaction Conditions

Reaction Steps

2.50 g (0.012 mol) of 3,5-di-tert-butylphenol and 1.27 g (0.013 mol) of triethylamine were dissolved in 15 mL of toluene followed by dropping in 1.45 g (0.013 mol) of methanesulfonyl chloride over the course of 10 minutes at 5° C. Following completion of dropping, the mixture was stirred for 3 hours at 25° C. and the 3,5-di-tert-butylphenol was confirmed to no longer be present. The reaction liquid was placed in ice water and following separation of the organic layer, was washed twice with saturated brine followed by drying with MgSO4 and concentrating to obtain 3.21 g (yield: 98%) of 3,5-di-tert-butylphenyl methanesulfonate. A purified product crystallized with n-hexane (white crystals, melting point: 76° C.) was used in a battery test.
