摘要： A method for producing a fluoropolyether group-containing compound, comprising reacting a fluoropolyether group-containing compound (A) represented by the following formula:

        X 11 -(R 11 ) n11 -R F1 X 12      (1)

in the presence of a metal catalyst to form a fluoropolyether group-containing compound (B) containing two or more moieties derived from the fluoropolyether group-containing compound (A). Each of symbols is as defined in the description.
