TL;DR: Polymerization gave the corresponding ROMPgel and ROMPsphere reagents, the latter of which proved efficient as an immobilized catalyst for the sensitized production of singlet oxygen for the purification-minimized parallel synthesis of endoperoxides and ene adducts.
Abstract: [reaction: see text] Crossover Linstead macrocyclization of norbornenyl-tagged diaminomaleonitrile with dipropylmaleonitrile gave the corresponding magnesium diaminohexapropylporphyrazine, which was subsequently converted into its zinc seco-derivative. Polymerization gave the corresponding ROMPgel and ROMPsphere (ROMP = ring-opening metathesis polymer) reagents, the latter of which proved efficient as an immobilized catalyst for the sensitized production of singlet oxygen for the purification-minimized parallel synthesis of endoperoxides and ene adducts.

TL;DR: Reductive deselenation of selenodiazole-fused porphyrazines was used to prepare macrocycles bearing two Collins ligands, two oxamido residues, or two quinoline-2-carboxamido units to prepare mixed peripheral ligand systems including a dimetallic picolinamido-Schiff base Porphyrazine.
Abstract: Reductive deselenation of selenodiazole-fused porphyrazines, followed by acylation of the resultant labile porphyrazinediamines, was used to prepare macrocycles bearing two Collins ligands, two oxamido residues, or two quinoline-2-carboxamido units. Peripheral coordination of copper(II) to the di-(quinoline-2-carboxamido)-porphyrazine gave a metal-linked face-to-face porphyrazine dimer array. Sequential derivatization of the two amino groups in the porphyrazinediamines was used to prepare mixed peripheral ligand systems including a dimetallic picolinamido−Schiff base porphyrazine. Such systems exhibit strong metal−metal spin coupling and are anticipated to be of value in the synthesis of novel electronic and magnetic materials.

TL;DR: In this paper, a crossover Linstead macrocyclization of norbornenyl-tagged diaminomaleonitrile with dipropylmaleonitriles gave the corresponding magnesium diaminohexapropylporphyrazine, which was subsequently converted into its zinc seco-derivative.
