polymerisierbare with cationic mixtures containing selected belarus.

摘要

Compounds of the formula I are described [R1(FeIIR2a]q+ananX-q(I) in which a is 1 or 2, n is 1 or 2, R1 is a substituted or unsubstituted pi -arene, R2 is a substituted or unsubstituted pi -arene or cyclopentadienyl anion or indenyl anion, q is an integer from 1 to 3, and X is FSO-3 or a q-valent anion of an organic sulfonic acid or of a carbocyclic acid; R1 can also be a polymeric, aromatic ligand. The invetion particularly relates to the compounds of the formula I wherein a is 1 and q is 1 and X-is an anion of a carbocyclic aromatic or heterocyclic aromatic sulfonic acid, selected from the group consisting of benzenesulfonic, toluenesulfonic, ethylbenzenesulfonic, isopropylbenzenesulfonic, dodecylbenzenesulfonic or dimethylbenzenesulfonic acid, 2,4,6-triisoporpylbenzenesulfonic acid, 2,4,6-trimethylbenzenesulfonic acid, naphthalenesulfonic acid, naphthalenedisulfonic acid, and naphthalenetrisulfonic acid, and the corresponding alkylated or partly fluorinated or perflourinated derivatives thereof; pyridinesulfonic, thiophenesulfonic, and pyrrolesulfonic acid and the corresponding partly fluorinated or perfluorinated derivatives of these acids. Cationically curable materials can be initiated (e.g., by irradiation or heat) in particular for the production of coatings having a good resistance to heat.
