Abstract

Compounds are used as catalysts according to general formula (1) M+x(C(SO2CF3)3)x, whereby x is equal to 1 or 2; M represents one hydrogen or alkaline metal atom when x equals 1; and M represents one alkaline-earth metal atom when x equals 2. The invention also relates to a novel Mg compound of formula (1).
