Abstract

The ESIMS technique, combined with 1H NMR evidence, provides a precise inventory of the catalytic TiIV precursors and the characterization of the reactive peroxometal complex involved in enantioselective sulfoxidation employing the TiIV–homochiral trialkanolamine–alkylhydroperoxide system.
