There is disclosed a process for the preparation of compounds of formula I [R Fe R2]q�Xq(I), wherein R is an anion of formula C5H4R1 or C9H7, R1 is hydrogen, C1-C6-alkyl or halogen R2 is a p5H4R3)Fe(C5H4R1) or (C9H7)2Fe, in which R3 has one of the meanings of R1, with at least one mole of a p2, followed by the optional replacement of the anion Xqin a manner known per se, the reaction of the ferrocene or ferrocene derivative being carried out in the presence of a) at least 1.2 mol of a mixture of Al trihalide and Zr(IV) or Hf(IV) tetrahalide, in the presence or absence of a metallic reducing agent, such that at least 0.2 mol of Zr(IV) or Hf(IV) tetrahalide and at least 0.1 mol of Al trihalide are present, or of b) at least 1.0 mol of a Zr(IV) or Hf(IV) tetrahalide as sole Lewis acid in conjunction with at least 1.0 mol of a metallic reducing agent, the amounts being based in each case on 1 mol of ferrocene or a ferrocene derivative. The compounds of formula I containing non-nucleophilic anions can be used as photoinitiators for cationically polymerisable compounds.
