A novel process for the preparation of thioethers comprising reacting a silylated thiol of the formula R--S--SiR.sub.1 R.sub.2 R.sub.3 I wherein R is an organic group and R.sub.1, R.sub.2 and R.sub.3 are individually selected from the group consisting of alkyl of 1 to 4 carbon atoms with an organic halide, sulfate or sulfonate in the presence of hexamethylphosphoric triamide as a solvent or co-solvent preferably under neutral conditions in aprotic solvents at a temperature between 0.degree. and 150.degree. C.
