Abstract
Vilsmeier reaction of mono-Ni 1,2-ethanebis(octaethylporphyrin) favour ed 10-substitution. Functional group interconversions led to pure 10-d imethylaminomethyl, -azomethine, -methoxymethyl, and -formyl derivativ es. Demetallation gave a range of labile 10-substituted free base dime rs. Oxidation of the mono-Ni compounds in AcOH gave the corresponding trans-ethylene mono-Ni derivatives, while the free bases were all conv erted to 10'-formyl-1,2-ethylenebis(octaethylporphyrin) under the same conditions.
