| Abstract: | In the presence of potassium carbonate, N, N-dimethylamino thio-carbonyl thiomethyl triphenylphosphonium bromide can form the corresponding ylide in situ, which can undergo Wittig reaction with aldehydes to give vinyl dithiocarbamates in high yields. If the esters were hydrolysized in the presence of mercuric chloride, a new method to lengthen aldehydes by one carbon atom was accomplished. |
