Phosphine-dependent selective cross-dimerization between terminal alkylacetylene and silylacetylene by iridium(I) guanidinate complex-phosphine system.
[摘要]：A new iridium(I)-guanidinate complex was prepd. and a crystal structure was done. The complex served as an efficient catalyst for phosphine-dependent selective cross-dimerization between silylacetylene and terminal alkyl- or arylacetylene. In cross-dimerization between silylacetylene and alkylacetylene, E/Z selectivity of resulting enynes could be controlled by changing the phosphine.
