The action of alkanethiols on bromomethylidynetricobalt nonacarbonyl in the presence of the triethylamine gives thioesters, RSC(O)CCo3(CO)9, as principal products, but arenethiols react to give tars. A more useful reactions is that between arenethiols and ClCCo3(CO09, which gives ArSCCo3(CO)9 complexes as the principal products.
