PURPOSE:To economically improve the yield of the titled compound useful as a starting raw material for surfactant, etc., by reacting perfluoro-2- methylpent-2-ene with a benzyl bromide derivative in a specific solvent in the presence of potassium fluoride. CONSTITUTION:The objective compound of formula II can be produced by reacting (A) 1mol of perfluoro-2-methylpent-2-ene with (B) preferably about 0.5-2mol, especially about 0.5-1mol of a benzyl bromide derivative of formula I (R is H, p-CN, m-CN, o-CN, p-NO2, m-NO2, o-NO2, p-CH2Br, m-CH2Br) in dimethylformamide solvent in the presence of potassium fluoride preferably at about 80-130 deg.C. The amount of potassium fluoride is preferably about 1-2mol per 1mol of perfluoro-2-methylpent-2-ene. |
