This patent describes a disproportionation process which comprises contacting at least one olefin from the group consisting of: acyclic mono- and polyenes having at least 3 up to 10 carbon atoms per molecule, and cycloalkyl and aryl derivatives thereof; cyclic mono- and polyenes having at least 4 to 10 carbon atoms per molecule, and alkyl and aryl derivatives thereof; mixtures of two or more of the above olefins; and mixtures of ethylene with one or more of the above olefins capable of undergoing disproportionation with a tungsten oxide on silica disproportionation catalyst system under disproportionation conditions, the improvement comprising contacting the catalyst with an activating amount of at least one alkyne conforming to the formula: R-C=C-R wherein each R is independently H or a C/sub 1/-C/sub 6/ carbon radical per mole of tungsten oxide.
