Abstract
A series of secondary methanols bearing ferrocenyl and a hetaryl substituent was tested in reactions with Lawesson’s reagent (LR) aimed at the preparation of respective methanethiols. The study showed that in boiling toluene after only few minutes the starting alcohols were consumed and unexpectedly, depending on the type of hetaryl substituent, tetra-substituted ethane or disubstituted methane derivatives were obtained in good to excellent yields. The presence of the ferrocene moiety is crucial for the observed reaction courses.
