Article abstract of DOI:10.1246/bcsj.55.1977

Several 2-alkylthio- and 2-arylthio-1,3-dithiolanes were synthesized by the reaction of 2-ethoxy-1,3-dithiolane with aliphatic and aromatic thiols in the presence of ZnCl2.The lithiation of 2-alkylthio-1,3-dithiolanes with butyllithium in tetrahydrofuran followed by the addition of alkyl halides gave unsymmetrical dialkyl trithiocarbonates in moderately good yields.
