Abstract: | The complex Ru(CO)3(PPh3)2 catalyzes the dimerization of methyl acrylate at 120–140°C to give tail-to-tail dimers containing predominantly dimethyl
(E)-2-hexene-1,6-dioate together with small amounts of trimers and polymer. The reaction under hydrogen atmosphere selectively
gave tail-to-tail dimers in improved yield without formation of trimers and polymer. Under these conditions a catalyst turnover
number of 246 was obtained at 130°C in 6 h. |
