| An investigation of the addition of nucleophiles to various diamagnetic and paramagnetic [MII(OEOP)](OAc) (OEOP is the monoanion of octaethyl-5-oxaporphyrin) (M = ZnII, CoII, Fe II and FeIII) complexes. In general, the reactions studied produce helical ring-opened complexes, which are sensitive to acidic conditions and demetallate. The list of nucleophiles include CH3O −, CH3S−, (CH3) 2N−, CN− as well as the chiral alkoxides of butanol and menthol.; The oxidation of ClFeIII(OEP) (OEP is the dianion of octaethyl porphyrin) in methanol by cyanide and ascorbate in a coupled fashion produces a myriad of different colored products. A few of these have been isolated and structurally characterized including H3(OEB-4,5-(OCH3 )2) and H2(OEB-15,19-(CN)2) (OEB is the trianion of octaethylbilindione). The chirality introduced in H3 (OEB-4,5-(OCH3)2) gives rise to a new diastereomer that can be isolated and characterized crystallographically. This is compared to previously isolated structures.; A separate project involves the exploration of porphyrins that contain benzyl groups with the hopes of co-crystallizing C60, C70 or C60O in the solid state. The isolation of RuII (TBzP)(CO)(CH3OH), NiII(TBzP) and Co II(TBzP) (TBzP is the dianion of tetrabenzyl porphyrin) were achievable, however, co-crystallization with a fullerene or fullerene-epoxide did not meet with success. |
