Reaktionsschritte

10 g of methyl 9-decenoate (54 mmol) purified on alumina, 18.1 g of 3,3-dimethyl-1-butene (neohexene, 215 mmol, 4 equivalents) and 100 g of toluene are placed in a 250 ml 10 glass reactor purged with nitrogen. The mixture is heated at 40° C., followed by addition, over a period of 2 hours, of 3.4 mg of catalyst M73-SiPr supplied by the company Umicore (75 ppm mol) dissolved in 5 ml of toluene. At the end of the addition, the degree of conversion of the methyl decenoate, measured by CPG, is 86%. The selectivity toward cross metathesis product is 35%.
