WebA phenyl is a hydrophobic group. Phenyl groups sometimes resist oxidation and reduction. Phenyl groups (like all aromatic compounds) have elevated stability relative to equivalent bonding in aliphatic (non-aromatic) groups. This improved stability is due to the unique characteristics of aromatic molecular orbitals. http://chemistry2.csudh.edu/rpendarvis/PhEffects.html

WebGilman reagent. A Gilman reagent is a lithium and copper ( diorganocopper) reagent compound, R 2 CuLi, where R is an alkyl or aryl.
