実験手順

Phenol (2.0 g) in 15 ml of tetrahydrofuran (THF) was slowly added to sodium hydride (1.0 g, 60% in oil) suspended in 5 ml THF at 0° C. Fifteen minutes later, 3.0 g of butyl 2-methylene-3-acetoxy-4,4,4-trichlorobutyrate (crude, GC: 86%) in 10 ml THF was slowly dropped into the phenoxide solution. The reaction was stirred at 0° C. for 3 hours and then permitted to warm to room temperature. The reaction was worked up by addition of 50 ml of water and 50 ml of ether. The organic layer was separated and the solvents were removed by vacuum. The resulting yellow oil was transferred to an alumina column and the product was eluted out with hexanes. A slightly yellow oil was obtained after removal of the hexanes, 3.1 g. The product was confirmed by NMR spectroscopy to be butyl 2-methylene-3-phenoxy-4,4,4-trichlorobutyrate.
