Selective cis-isomerisation of but-1-ene by homogeneous catalysis with triphenylphosphinenickel complexes
Abstract
The treatment of but-1-ene with a mixture of tin(II) chloride and triphenylphosphinenickel complexes prepared from (PPh3)2NiX2(X = Cl, Br, I), PPh3, and zinc leads to selective cis-isomerisation.
