The First Direct Synthesis of Corroles from Pyrrole.
The solvent-free, catalyst-free condensation of pyrrole and aldehydes provides an extremely facile synthetic pathway to novel corroles, including an ionic, water-soluble corrole.
Solvent-Free Condensation of Pyrrole and Pentafluorobenzaldehyde: A Novel Synthetic Pathway to Corrole and Oligopyrromethenes
The solvent-free condensation of pyrrole and pentafluorobenzaldehyde (and to a lesser extent other electron-poor aldehydes as well) leads to a variety of products, of which three have been isolated
First catalysis by corrole metal complexes: epoxidation, hydroxylation, and cyclopropanation
The first ever application of corroles shows that their metal complexes are good catalysts, almost as potent as the corresponding metalloporphyrins in the oxygenation of hydrocarbons by
Coordination chemistry of the novel 5,10,15-tris(pentafluorophenyl)corrole: synthesis, spectroscopy, and structural characterization of its cobalt(III), rhodium(III), and iron(IV) complexes.
The syntheses and characterization of the cobalt(III), rhodium(III, and iron(IV) tris(pentafluorophenyl)corrole, including the X-ray structures of the last two are presented.
Metalloporphyrin catalyzed asymmetric cyclopropanation of olefins
Abstract Asymmetric cyclopropanation of styrene by an enantiopure carbenoid under catalysis by simple metalloporphyrins was found to be much more efficient and selective than the alternative
Evaluating the impact of pretreatment processes on fouling of reverse osmosis membrane by secondary wastewater
Abstract Pretreatment of secondary effluents, containing relatively high concentrations of colloidal particles, suspended solids, dissolved organics and high level of biological activity, is required
A novel synthesis of protected glucose intermediates
The 1,2,4,6-Tetra-O-pivaloyl-D-gluco-pyranose 3 and 1,2,3,6-Tetra-O-pivaloyl-D-gluco-pyranose 4 have been prepared in one step from anhydrous glucose and pivaloyl chloride. These new intermediates
Stereoselective cyclopropanation with a sultam carbenoid
Abstract Stereoselective cyclopropanation of alkenes with the Oppolzer's sultam carbenoid was examined for the first time. The addition reaction proceeds in high yields on substituted alkenes and
Synthesis and utilization of saccharide intermediates.
A new method has been developed for preparation of partially pivaloylated saccharides in one step from readily available starting materials. These intermediates were used in the synthesis of
Highly efficient trapping of short-lived 1,4-diradicals, the order of first bond formation in the intramolecular photocycloaddition of 3-(4′-pentenyl)-cyclohex-2-enones
Abstract Complete trapping of 1,4-diradical intermediates, formed in the intramolecular [2+2] photocyclo-addition of 13, provide direct evidence for the exclusive formation of the first bond at the
