Synthesis of Halomethyl and Other Bipyridine Derivatives by Reaction of 4,4‘-Bis[(trimethylsilyl)methyl]-2,2‘-bipyridine with Electrophiles in the Presence of Fluoride Ion

Autor: Cassandra L. Fraser, Natia R. Anastasi, Jaydeep J. S. Lamba

Publikováno v: The Journal of Organic Chemistry. 62:9314-9317

Bipyridine (bpy) ligands figure prominently in many areas of chemistry. Common precursors to many derivatives are the halomethyl-substituted analogues. This report describes a new, high yield route to these valuable compounds via a trimethylsilyl (TM

Imine-Bridged Planar Poly(p-phenylene) Derivatives for Maximization of Extended .pi.-Conjugation. The Common Intermediate Approach

Autor: James M. Tour, Jaydeep J. S. Lamba

Publikováno v: Journal of the American Chemical Society. 116:11723-11736

Described are two approaches to planar conjugated poly(p-phenylene) (PPP) derivatives. The first approach, involving lactam bridges, was unsuccessful due to the insolubility of the 6(511)-phenanthridinonyl moieties. The second approach, which utilize

Synthesis of planar poly(p -phenylene) derivatives for maximization of extended π-conjugation

Autor: Jaydeep J. S. Lamba, James M. Tour

Publikováno v: Macromolecular Symposia. 77:389-394

Described is the synthesis of a ladder polymer with a poly(p-phenylene) (PPP) backbone. The main PPP backbone was synthesized via palladium-catalyzed coupling of an arylbis(boronic ester) with an aryl dibromide. Imine bridges, formed by exposure of t
