Reaction Conditions:

[1,3-bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]dichloro-(3-phenyl-1H-inden-1-ylidene)(tricyclohexylphosphine)ruthenium(II) in toluene at 50; for 5 h;

Steps:

1.c
c) Hex-3-ene-l,6-dicarboxylic acid; 1.00 g (11.62 mmol) of 3-butenoic acid (90 %, Acros Organics) and 0.22 g (0.23 mmol, 2.00 mol%) of Neolyst M2 SIMES (Umicore) are stirred in 10 ml of toluene (99+ %, Acros Organics) at a reaction temperature of 50 °C for five hours at a stirring speed of 900 rpm under reduced pressure. The residue is washed with 15 ml of n-pentane and dried under reduced pressure at a temperature of 40 °C. 0.42 g (2.96 mmol; 51 %) of a white solid is obtained. The hex-3-ene-l,6-dicarboxylic acid is stored in a refrigerator under an argon atmosphere.
