Potassium 1-piperidino-2-H(alkyl,aryl)ethenethiolates react with phenyl isothiocyanate and phenyl isocyanate, forming 2-H(alkyl,aryl)-N,N-pentamethylene-N'-phenyldiamides of dithiomalonic and thiomalonic acids respectively.In the reaction of potassium 1-piperidino-2-phenylethenethiolate with phenyl isothiocyanate 5-piperidino-4-phenyl-3-phenylimino-1,2-dithiole is also formed.This compound and also 4-H(alkyl)-5-piperidino-3-phenylimino-1,2-dithioles were obtained by oxidation of substituted amides of dithiomalonic acid described above in the presence of triethylamine.Cyclohexylcarbodiimide does not react with potassium 1-piperidino-2-phenylethenethiolate.
