PROCESS FOR THE PREPARATION OF PLATINUM OR PALLADIUM BENZOPORPHYRINS AND PLATINUM OR PALLADIUM CYCLOHEXENOPORPHYRINS, INTERMEDIATES, AND AN OXYGEN SENSOR COMPRISING PLATINUM OR PALLADIUM CYCLOHEXENOPORPHYRIN

摘要

Compounds of formula (I) wherein Me is Pd(II) or Pt(II); R is H or C1-C18alkyl, or is C3-C8cycloalkyl, phenyl, pyridyl or phenyl-C1-C4alkylene, each of which is unsubstituted or substituted by C1-C18alkyl, C1-C18alkoxy, R3-O-C(O)-, halogen, -CN or by -NO2; R1 and R2 are each independently of the other H, C1-C12alkyl or C1-C12alkoxy, or R1 and R2 together are -OCH2O-, -OCH2CH2O- or -CH=CH-CH=CH-; and R3 is C1-C18alkyl, C3-C8cycloalkyl, phenyl, benzyl, C1-C12alkylphenyl or C1-C12alkylbenzyl. Compounds of formula (I) are valuable luminophores and/or intermediates for the preparation of palladium(II) or platinum(II) benzoporphyrins, which are likewise luminophores.
