Versuchsvorschrift
To a stirred solution of 3-methyl butanol (2.0 g, 22.6 mmol) and acryloyl chloride (2.05 g, 22.6 mmol) in dichloromethane (5 ml) at 0° C. is added dropwise triethylamine (3.2 ml, 22.7 mmol). The solution is stirred for 30 minutes at room temperature and then concentrated to a residue. The residue is washed with hexanes (2×10 ml) and the resultant combined organics are concentrated and filtered through a plug of silica to give 3.0 g of 3-methylbutyl acrylate as an oil, 93% yield.
