[2,3-dimethylbutan-2-yl(dimethyl)silyl] trifluoromethanesulfonate

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 50 ml of trifluoromethanesulfonic acid are slowly added dropwise at room temperature under argon to 101.57 g (0.57 mol) of (1,1,2,2-tetramethyleth-1-yl)-dimethylchlorosilane. Subsequently, the mixture is heated for 8 hours at 60° C. After this time, the evolution of HCl ceases. 111 g (67% of theory) of a colourless oil of boiling point=123°-124° C./28.6 mbar are obtained by distillation. The 1H-NMR spectrum is in agreement with the structure. 111 g (67% of theory) of a colourless oil of boiling point=123°-124° C./28.6 mbar are obtained by distillation
