Abstract

Abstract: Dimethylacetylene (tolane) suffered hydrogenation in the presence of (RCp)₂TiCl₂. The influences of the catalyst structure on the selectivity of the reaction have been studied.Results indieated that cis-olefins as well as trans-olefins could be obtained by varying R in the catalyst and under suitable reaction conditions.

Key words: dimethylacetylene, hydrogenation, selectivity, catalyst, titan-hydrogen complex
