Abstract
Reaction products comprising ring-metalated porphyrins are provided that are useful in the synthesis of porphyrin polymers and porphyrins substituted with, for example, vinyl and acetylene groups.
Claims19
The product produced by a process comprising the steps of:
- providing a porphyrin compound having formula (1), (2), or (3):
- ##STR7## wherein M and M' are metal atoms and at least one of R.sub.A1 -R.sub.A4 or R.sub.B1 -R.sub.B8 is a halogen;
- and
- reacting said porphyrin compound with an alkyltin reagent.
