Abstract
Procedure for the preparation of alpha-mercapto-amides of the following structural formula ** (See formula) ** wherein R represents alkenyl or alkynyl and R 'represents hydrogen, alkyl or alkenyl, characterized in that a substituted acetic acid of the following structural formula ** (See formula) ** or it is treated with hydrogen sulfide, after which the alpha-mercapto-alpha, alpha-dialkyl-acetic acid is reacted with the halogenide of formula R-halogen in which R has the same significance as before, being transformed the alpha-alkenylmercapto- or alpha-alkynylmercaptoacetic acid thus formed in an acid halide and put into reaction with an amine of the formula H2N-R 'in which R' has the same meaning as before, or is transformed into the acid halogenide, after which the latter is reacted with an amine of the formula H2N-R 'in which R' has the same meaning as before, by reacting the acid amide formed with a compound of formula HS-R in which R has the same meaning as before.
