The synthesis of dimethyl-[ Slsulphide in high yield from the contact of hydrogen-[35s] sulphide and methanol over a Y A1203.1% Si02 catalyst is described.
The procedure produces high yields of dimethyl-[35Sl sulphide of low specific activity compared to that of the hydrogen-[3%1 sulphide starting material.

## Abstract A general method for the synthesis of [^35^S]phosphorothionates is proposed, based on the example of [^35^S]fenthion. This consists of reacting molecular ^35^S with the corresponding phosphites which are easily prepared from commercial precursors.
## Abstract A short and very convenient method is described for the preparation of cysteineβ^35^Sβsulfate using unlabeled cysteine βSβsulfate and Lβcysteineβ^35^S. This method provides an 80% yield and can be used for microquantity synthesis.
