(1) The authors would like to correct mistakes in the title paper [1]. The wrong central atom, P (phosphorus), in Scheme 8 has been corrected to S (sulfur), and the anion in the intermediate ion pair has been changed to CF3SO3−. The corrected Scheme 8 is presented below.
Scheme 8.
Interconversion of the enantiomers of optically active p-toluenosulfinylpyrrolidyne.
(2) Moreover, in the line below Scheme 9, the word ‘sulfonate’ has been corrected to ‘sulfinate’. The correct sentence should be as follows:
‘Then, the rate of racemization of the methyl sulfinate (+)-(R)−4 and the rate of the isotopic methoxyl–methoxy exchange in methanol in the presence of trifluoroacetic acid have been determined [18]’.
(3) In the References section the title of reference [17] contains the misspelled word: “Stom”. It should be: “Atom”.
The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original publication has also been updated.
