Procedure

Phenyl N-(4-iodophenyl)-3-(phenoxy)acrylimidate (0.50 g), bis(benzylideneacetone)palladium (0) (0.023 g) and cesium carbonate (0.82 g) were suspended to dioxane (15 ml). Tri-t-butylphosphine (10 wt % in hexane: 0.24 g) and tributyl(vinyl)tin (0.44 g) were added thereto and it was stirred for four hours at room temperature and 60° C. for five hours. The unsolved matter was filtered off, and the filtrate was concentrated under reduced pressure. The residue was separated and purified by silica gel column chromatography (hexane:ethyl acetate=30:1) to obtain phenyl N-(4-vinylphenyl)-3-(phenoxy)acrylimidate (0.29 g) as yellow oil.
