Abstract

An olefin-metathesis catalyst featuring a 1,3-bis(2,6-diisopropylphenyl)-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 10–20 times lower catalyst loading compared to the state of the art could be achieved.

Key words

catalysis - metathesis - enones - alkenes - ruthenium

  • 16 Typical Experimental Procedure A Schlenk tube was charged with 1 (Fluka, 98%, 0.84 g, 9.98 mmol), 2 (Aldrich, 99%, stabilized with 1000 ppm BHT, 2.10 g, 0.0299 mol), and dry, degassed Et2O (5 mL) under inert atmosphere of nitrogen. The reaction mixture was heated to 35 °C (oil bath temperature), the catalyst 6 (prepared according to ref. 18, 7.50 mg, 00998 mmol) was added, and the reaction mixture was kept at that temperature for 16 h. Afterwards, the reaction mixture was concentrated under reduced pressure to 1 mL and subjected to column chromatography (silica gel, eluent: cyclohexane). Drying of the appropriate fractions in vacuum yielded 3 as colorless oil in 92% yield. Reactions listed in Table 2 were carried out similarly. Always more than 90% isolated yield of the cross-metathesis products was obtained in all cases where full conversion was reached. Products were characterized by comparison of their chromatographic and spectroscopic with those described in the literature (ref. 3, 4, 15, and 18).
