Low Catalyst Loading in the Cross Metathesis of Olefins with Methyl Vinyl Ketone
摘要:
An olefin-metathesis catalyst featuring a 1,3-bis(2,6-di-isopropylphenyl)-4,5-dihydroimidazol-2-ylidene N-heterocyclic carbene and an ester-chelating carbene ligand efficiently promoted the cross metathesis of olefins with 3-buten-2-one in the presence of copper iodide as cocatalyst. At optimized reaction conditions a 1020 times lower catalyst loading compared to the state of the art could be achieved.
