Article abstract of DOI:10.1246/bcsj.59.1403

Wittig reaction of new phosphonium salts, (triphenylphosphonio)methyl arenecarbodithioate iodides, with variety of aldehydes gave the corresponding vinyl dithiocarboxylate with nucleophiles such as potassium alkoxide or alkanethiolate was investigated and found to give the thioacylated products in high yields.Ab initio molecular orbital calculations of the model compound vinyl dithioformate, are also discussed.
