Abstrakt: 1.The insertion of the dimethyl sulfoxide ligand into tris(triphenylphosphine)rhodium chloride and subsequent treatment with sodium borohydride in dimethyl sulfoxide solution increases the catalytic activity of the complex by several orders of magnitude in the reactions for shift of the terminal C=C bond and the cis-trans transformation ofß-olefins.2.Branching of the hydrocarbon chain of the olefin leads to a decrease in its isomerization rate.3.The isomerization rate increases sharply in the presence of hydrogen, which can serve as an indication of the intermediate formation of the hydride.
