Oxidation and Reduction
Abstract Polymer supported ruthenium catalyst 8 was found to be an effective catalyst for ring closing metathesis. The rate of reaction and activity was found to be comparable to that of homogeneousExpand
Hybrid Polymer/MOF membranes for Organic Solvent Nanofiltration (OSN): Chemical Modification and the Quest for Perfection
Abstract One of the main challenges in the field of Organic Solvent Nanofiltration (OSN) is to improve the selectivity of membranes, allowing the separation of closely related solutes. This objectiveExpand
Operation Mechanism of a Molecular Machine Revealed Using Time- Resolved Vibrational Spectroscopy
Rotaxanes comprise macrocycles that can shuttle between docking stations along an axle. We explored the nanosecond shuttling mechanism by reversing the relative binding affinities of two stationsExpand
Mechanistic and Performance Studies on the Ligand-Promoted Ullmann Amination Reaction
Over the last two decades many different auxiliary ligand systems have been utilized in the copper-catalyzed Ullmann amination reaction. However, there has been little consensus on the relativeExpand
Bromonium ion induced transannular oxonium ion formation-fragmentation in model obtusallene systems and structural reassignment of obtusallenes V-VII.
Ring-closing metathesis was used to construct the strained 11-membered ring of obtusallenes II (and IV). Bromonium ion induced transannular oxonium ion formation-fragmentation gave the macrocyclicExpand
Structural reassignment of obtusallenes V, VI, and VII by GIAO-based density functional prediction.
Revised structures proposed previously for obtusallenes V-VII ( 5- 7) have been confirmed on the basis of computed GIAO-DFT 13C NMR chemical shifts.

[Structure: see text] A hypothesis concerning the biosynthesis of the marine natural product family the obtusallenes is proposed. Multiple electrophilic bromination events are invoked.
Ortho-substituted iodobenzenes as novel organocatalysts for bromination of alkenes.
Suitably ortho-substituted iodobenzenes act as organocatalysts for the transfer of electrophilic bromine from N-bromosuccinimide to alkenes via the intermediacy of bromoiodinanes.
Intramolecular bromonium ion assisted epoxide ring-opening: capture of the oxonium ion with an added external nucleophile.
9-Oxabicyclo[6.1.0]non-4-ene (1) undergoes intramolecular bromonium ion-assisted epoxide ring-opening using N-bromosuccinimide via a presumed oxonium ion that is subject to stereospecific,Expand
