    Author: Li G, Mehta R, Srikrishnan T, Nurco DJ, Tabaczynski WA, Alderfer JL, Smith KM, Dougherty TJ, Pandey RK.
    Journal: Chem Commun (Camb); 2002 Jun 07; (11):1172-3. PubMed ID: 12109067.
    Abstract:
    Reaction of meso-(2-formylvinyl)octaethylporphyrin with (CH3)3SiCN-Cu(OTf)2 produced unexpected 10(3)-trimethylsiloxyl and 10(3)-hydroxyl fused propenochlorins which, in H2SO4, underwent subsequent migration of the 8-ethyl group to the 10(3)-position of the exocyclic benzene ring to form a novel benzochlorin.
