Reaction Steps

2.0 g (2 mmol) of platinum(II) tetraphenylcyclohexenoporphyrin according to Example B2 are mixed with 4.5 g (20 mmol) of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone and 400 ml of toluene, and the mixture is heated at reflux for one hour. After cooling, the reaction mixture is taken up in methanol and filtered. There are obtained 1.8 g of crude product, which is dissolved in chloroform and then subjected to flash chromatography on silica gel. The green eluates are combined and the chloroform is removed in vacuo at 60° C. 1.4 g (71%) of a microcrystalline green powder are obtained.
