| titleOfInvention | Process for the preparation of organometallic compounds |
| abstract | There is disclosed a process for the preparation of compounds of formula I n n [R Fe R.sup.2 ].sub.q.sup.⊕ X.sup.q⊖ (I), n n wherein R is an anion of formula C 5 H 4 R 1 or C 9 H 7 , R 1 is hydrogen, C 1 -C 6 -alkyl or halogen R 2 is a π-arene, X is an anion of valency q and q is 1, 2 or 3, by reacting ferrocene or a ferrocene derivative (C 5 H 4 R 3 )Fe(C 5 H 4 R 1 ) or (C 9 H 7 ) 2 Fe, in which R 3 has one of the meanings of R 1 , with at least one mole of a π-arene R 2 , followed by the optional replacement of the anion X q ⊖ in a manner known per se, the reaction of the ferrocene or ferrocene derivative being carried out in the presence of n 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 n 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. n The compounds of formula I containing non-nucleophilic anions can be used as photoinitiators for cationically polymerisable compounds. |
