Reactivity of β - Stannylketones . Elimination vs . Substitution

In the present work we report the results obtained in the reaction of βstannylketones (I) with t-BuONa in dimethylsulfoxide (DMSO) and acetonitrile (ACN) as solvents. The reaction mechanisms probably involved are proposed. Introduction In the reaction of β-functionalized organotin compounds (I) with t-BuONa in t-BuOH there is a competition between an elimination reaction [(E1cB)R], leading to o...

Nucleophilic Substitution and Elimination

What does the term "nucleophilic substitution" imply? • A nucleophile is an the electron rich species that will react with an electron poor species • A substitution implies that one group replaces another. Nucleophilic substitution reactions occur when an electron rich species, the nucleophile, reacts at an electrophilic saturated C atom attached to an electronegative group (important), the lea...

Lewis Basicity of Nitrogen-Doped Graphite Observed by CO2 Chemisorption

The characteristics of CO2 adsorption sites on a nitrogen-doped graphite model system (N-HOPG) were investigated by X-ray photoelectron and absorption spectroscopy and infrared reflection absorption spectroscopy. Adsorbed CO2 was observed lying flat on N-HOPG, stabilized by a charge transfer from the substrate. This demonstrated that Lewis base sites were formed by the incorporation of nitrogen...
