1-[5-Acetyl-3-(methylthiomethyl)tetrahydro-3-thiopyranyl]-1-ethanone was obtained by the interaction of sodium sulfide and sodium methanethiolate with formaldehyde and acetone. The intramolecular crotonate condensation of the product leads to 4-methyl-1-m

Thiomethylation of propanone with formaldehyde and sulfides of spent akaline solutions that contain predominantly sodium mercaptide is studied. It is demonstrated that thiomethylation results for the most part in a mixture of mono- and bis(methylthiomethyl)propan-2-ones (76 wt %) at 20°C and leads to the formation of 4-methyl-5-(methylthiomethyl)-7-thiabicyclo[3.3.1]non-3-en-2-one (52 wt %) and an increase in the fraction of tris- and tetrakis(methylthiomethyl)-substituted propanones at 80°C.
