## Abstract Carbonyl sulfide (COS) was prepared by a replacement reaction from potassium thiocyanate (KSCN) in 50% sulfuric acid. ^14^CβCOS or ^35^SβCOS can be prepared by the same method, depending on the position of the label in the starting KSCN. The yield of the final product is in excess of 60

## Abstract DLβ[2β^14^C]Octanβ2βsulPhate was prepared by sulphating DLβ[2β^14^C]octanβ2βol with pyridineβSO~3~ adduct. Synthesis of the DLβ[2β^14^C]alkanol started with carboxylation of hexyl magnesium bromide with ^14^CO~2~. Subsequent methylation with diazomethane and reduction of the ester with
