Participants

Reaction Steps

To a solution of trifluoro-methanesulfonic acid 3-allyloxy-4-vinyl-phenyl ester (0.68 g, 2.2 mmol) in dichloromethane (5 ml) was added Ru-catalyst (Grubb's catalyst) (36 mg, 2 mol %), and the reaction mixture was stirred for 2 h at room temperature. After that period the reaction was complete (GC) and the reaction mixture was used in the next step without any work-up. Analytical sample was obtained after removal of the solvent by silica gel column chromatography (EA:Hex, 1:20).
