  The preparation of O-alkyl carbonochloridothioates (2) was improved by performing the reaction of thiophosgene with potassium alkoxides in the corresponding alcohol or in tetrahydrofuran at - 65°C for 1 hour. In all cases, the reaction yielded products 2, O,O-dialkyl carbonothioates (4), and dialkyl carbonates (5) in varying distribution.
