Abstrakt: 1.A method was developed for the catalytic hydrogenation of the triple bond in 1-alkyl(aryl)thio-1-buten-3-ynes in order to obtain 1-alkylthio-1,3-butadienes.2.The most suitable catalyst for the reduction of di-unsaturated sulfides is the Pd — B catalyst.3.The addition of hydrogen to 1-alkyl(aryl)thio-1,3-butadienes goes in the 3,4 position with the formation of 1-alkyl(aryl)thio-1-butenes.
