Single And Double Nucleophilic-Addition To Coordinated Pi-Hydrocarbons - Manganese-Mediated Functionalization Of Arenes, Robert D. Pike, D. A. Sweigart

Arts & Sciences Articles

A range of carbon-donor nucleophiles add to the arene ring in (arene)Mn(CO)2L+ cations to give neutral cyclohexadienyl complexes that liberate monofunctionalized arenes upon oxidative removal of the metal. Treatment of the cyclohexadienyl complexes with the nitrosonium salt NOPF6 affords cationic metal nitrosyl complexes that are attacked by a second nucleophile to give cis- and trans-difunctionalized 1,3-cyclohexadienes. When the metal center is chiral, this procedure provides a route to enantiomerically pure cyclohexadienes. 1. Introduction 2. Mechanism of Nucleophilic Addition 3. Single Nucleophilic Addition 4.

Atmospheric Input Of Polycyclic Aromatic Hydrocarbons To The Sea Surface Microlayer, Lino J. Gallo Jan 1990

Atmospheric Input Of Polycyclic Aromatic Hydrocarbons To The Sea Surface Microlayer, Lino J. Gallo

Dissertations, Theses, and Masters Projects

Atmospheric input of polycyclic aromatic hydrocarbons (PAH) to water was studied and the effects of sea surface microlayer (SSM) determined. The York River system and the Perrin River areas were monitored with a drum skimmer and a high volume air sampler. Experiments were conducted in the laboratory under controlled conditions. The SSM extracted vapor phase PAH of low molecular weight from the air, and there, aromatic compounds went from dissolved into particulate phase very rapidly. Water covered with a natural SSM received much less atmospheric input of PAH than water without SSM in a given period of time. Henry's law …
